Fedora :: Cannot Wake From MCE Remote In New Kernel?
Jul 17, 2010
I am running a Fedora 12 installation in my bedroom as a slave mythtv frontend. I have set it up to be able to put the PC to sleep and wake up with a MCE remote. This has been working for near on a year now with no issues. Yesterday I did a yum update and ended up with kernel 2.6.32.16-141.fc12.i686.PAE (up from 2.6.32.12-115.fc12.i686.PAE)
Now everything seems to work fine however I can put the PC to sleep with the remote but I cannot wake it up with the remote. a cat of /proc/acpi/wakeup shows
Code:
DeviceS-state Status Sysfs node
SMB0 S4 disabled pci:0000:00:03.2
USB0 S4 enabled pci:0000:00:04.0
USB2 S4 enabled pci:0000:00:04.1
US15 S4 enabled pci:0000:00:06.0
[Code]...
At the grub prompt if I select the old kernel 2.6.32.12-115.fc12.i686.PAE then the computer will start up with no graphical prompt (need to figure out how to work kmod-nvidia i guess), but I can use the remote to put the pc to sleep and wake it up again. Also using the old kernel and telneting into the PC I see that /proc/acpi/wakeup is no different. Does anyone have any clues on hoiw to get wakeup to work with this new kernel? Or how do I roll back everything to the older kernel and get my graphics driver back (i tried to reboot with old kernel and then yum erase kmod-nvidia-PAE and then yum install kmod-nvidia-PAE but no luck.
Another thing worth noting is that I can wake the computer with the power button, just not the USB remote. THere is also nothing in the motherboard bios for setting wake on USB.

I am trying to conserve electricity and was looking for a linux WOL app that will allow me to remotely wake my windows 7 computer so I can stream music on demand. I have to believe this exists/is possible. I am also an idiot so if there is such a thing I'm going to need help getting it up and running.

I have an interesting issue. I have a computer running Ubuntu 10.10. I have a wireless USB Microsoft keyboard attached to this, and I have a cheap USB infrared remote also attached to it.The wireless USB Microsoft keyboard can wake up the system from suspend. The USB infrared remote cannot.To start off, I made sure my /proc/acpi/wakeup had wakeup enabled for all usb devices.
Code:
xbmc:~$ cat /proc/acpi/wakeup
Device S-state Status Sysfs node

I've had this problem two times before and solved it once by following a guide, the other time by formatting. It always happens when it fails to wake up from suspend. Usually I am unable to even mount the drive or access the files. This one is different in that now I can actually access my files for the most part but this comes up on boot. I backed up most of my files (except it still says I don't have permission to access some of them) but I would like to get it back up and running without formatting. If I boot in recovery mode it stops at this. I took a picture but I rewrote some of it here.

Running Fedora 12 with all the latest updates installed.
Using Radeon card with the experimental Mesa 3D driver. (The opensource stuff rather than ATi's closesource driver.)
Most of the time when it goes into screensaver, and turns off the monitor, it can't be wake up again.
The OS is still running, I can access it's web server, ssh, everything, just can't use the desktop!!
I have tried nomodeset and pcie_asm=off in grub but neither of them fixes the problem.
What else should I try?

I've ran "powertop" on my computer and it showed horrible amount of wake-ups per second:
Code:
Cn Avg residency P-states (frequencies)
C0 (cpu running) (26.7%) 2.81 Ghz 100.0%
polling 0.0ms ( 0.0%) 1400 Mhz 0.0%
C1 16.2ms (60.5%) 1050 Mhz 0.0%
C2 0.0ms (12.8%) 700 Mhz 0.0%
350 Mhz 0.0%
Wakeups-from-idle per second : 63944.8 interval: 5.0s
no ACPI power usage estimate available
Top causes for wakeups:
45.1% ( 15.6) <interrupt> : pata_atiixp
26.0% ( 9.0) <kernel core> : hrtimer_start_range_ns (tick_sched_timer)
9.2% ( 3.2) <kernel core> : hrtimer_start (tick_sched_timer)
5.8% ( 2.0) <kernel core> : add_timer_on (clocksource_watchdog)
1.7% ( 0.6) <interrupt> : ohci_hcd:usb4, radeon, yenta
1.7% ( 0.6) Xorg : queue_delayed_work (delayed_work_timer_fn)
Suggestion: increase the VM dirty writeback time from 5.00 to 15 seconds with:
Echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
This wakes the disk up less frequently for background VM activity
Q - Quit R - Refresh W - Increase Writeback time
If I wait it decreases to 50000, but it is still huge!
Situation is duplicated after complete F12 re-install. All defaults are used and no changes performed after install. Just checked again and let computer run idle for a while. Powertop reports 79604 wake-up per second, even more than before. Again, the top cause is "pata_atiixp". Also, performing suggestions of powertop shown at the bottom of the program does not help either. That decreases wake-up by a few hundreds only. Wake-ups are still well over 50000.

I been a windows guy forever, and wanted to make the switch. Anyways, I am hoping to do a wireless wake-on-lan from a windows box. I have an older laptop that has a dead screen and I am trying to use it as a server. So, I want to be able to VNC the linux box from my vista machine. I think that's going to be straight forward. But, the linux machine doesn't have a builtin wireless card, so I am using a USB wireless deal. If I let the laptop hibernate/sleep after being idle, can I wake from my vista box over my network?

I've configured my F12 system to go to sleep when idle for a period of time and so far everything has been working out well except that it appears that the USB ports are completely dead with the system is put into sleep. I can't wake it using keyboard or mouse. only with the power button. Anyoen else experience this or know how to allow sleep from keyboard/mouse?

goes to sleep just fine but won't wake up... in Windows, I see that it only supports Sleep Mode S3, which it calls hybrid sleep. I know that the video driver is the key to getting it working properly in Windows, I can get the exact name of the driver if needed but I do know it is nVidia.

I have a feature that keeps me going back to Mac every night, and I was wondering if there was an equivalent. I have a nice app called alarm clock on Mac that plays music from my library on specified days of the week and times AND can wake the computer from sleep to do so. I was wondering if there was a Linux equivalent, such as crontab, that could do all those things. It's the last barrier to almost full time Linux use.

I have a Fedora server at home. I don't want it to be running all the time to reduce the power usage and be more green It only works , whet it is really needed. So when it is not in use (no ssh or http connections have been active for some time), a custom python script suspends it. I have set it to wake up on unicast messages, so when somebody connects to it, the server wakes up.In Fedora 12 everything worked fine: when the server was sleeping and you connected to it using ssh or a web browser, the client waited for couple of seconds until the server was up and then connected (actually it worked even when server was turned off: the command "ssh [user]@[server]" just waited until server was booted up and then connected.)
Now I installed Fedora 13 on the server. When I try to connect to the server when it's sleeping, the client waits for some time (and server wakes up), then the connection just times out. When I try to connect again, it works. When server is up and running, I can connect to it. So when it is sleeping I have to connect twice: first to wake it up and then connect again to log in.Do you have any ideas what is causing this problem, as it is really annoying for me and I don't want to have it running all the day.Also, I have not set up the network in the best way, I think. To start the network at boot, i have put the command
Code:
ifup eth0
to /etc/rc.local.
To start the network when resurming from suspend, I have creted a script with the same command in /usr/lib64/pm-utils/sleep.d. It works, but it does not seam to be the *right* way to do this. Maybe this is also causing the first problem. So how have you managed to get a working network connection on your Fedora 13 headless server?

We're using both SuSe and RHEL servers. Our servers are running behind firewall device and remote root login is disabled in SSH.
We're using NAT.
Remote client connections including failed logins are logged into the /var/log/messages but what is logged are gateway ip of our LAN - the LAN IP of Firewall device.
How can I logged the external or public IP of the remote client?

I have two problems. I installed a RHEL variant (scientific linux) on an already dual boot system with ubuntu and vista.
It replaced GRUB with (I think an older) GRUB version and to add to that I cannot see my ubuntu ditro anymore. is there a way of reinstalling the GRUB that came with ubuntu then adding the RHEL distro to it?
my second problem is that I cannot figure out how to enable wake on lan in scientific linux (RHEL). on ubuntu I would just write a small script and update all runlevels to run it at startup. what is the alternative on redhat?

I want to remotely install OpenSUSE on one of my servers. I followed the instructions given at SDB:Remote installation - openSUSE, but it didn't work. (My server reverted back to the already installed system.) I think this has to do with a special kernel module (megaraid_sas) that is necessary for the raid controller. Without this module, the kernel cannot find any disk. Of course, the module is not included in the initrd provided by OpenSUSE. I know how to add files to the initrd, but I have no idea where I have to put the required kernel module and which config file inside the initrd must be modified to make the kernel load the module.

my problem is on installing nvidia driver on fc12 32bit but, first of all, as i understood the pae kernel requires more than 4gb of ram,i have a 2.2 ghz cpu with 2 gb ram,but when i run command:uname -r it answers: 2.6.31.5-127.PAE [i have fc12 32 bit] when we try to download linux we have a 32bit edition or 64bit edition,do we have an edition which is only for pae? or when we install for example the 32bit edition on a computer with more than 4gb of ram then the kernel automatically will change to be a pae kernel??

I'm I seeing this wrong or is the initrd file in kernel-2.6.27.25-170.2.72.fc10.x86_64 a zero byte file and that's why I can't boot with it( get this "kernel panic not syncing VFS unable to mount root fs on known -block (0,0)" message)

there is an issue with the way the Linux Kernel addresses memory by default and the graphic drivers for my Asus G1Sn. I have a patch that I had compiled against a custom kernel for 2.6.27.xx how ever it does not work with the latest kernel in Fedora 11. It is beyond me to rewrite the patch to work with a different kernel.

I use a pretty fresh installed RHEL 5.4, which should be very similar to Fedora. After the basic installation I installed xen and xen-kernel via yum with no errors. I can select the xen-kernel at boot time. But after booting the normal kernel shows up.
[root@noname boot]# uname -r
2.6.18-164.11.1.el5
My /boot/grub/menu.lst looks like:
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
[code]....
I can't see anything wrong and I did not change/try anything.

I've been using Fedora 12 for about a month, and i'm very happy with it. Even tough, there's only one thing that worries me, and is giving me problems at the same time. I'm getting an error from: syslog@localhost that says: kernel:Uhhuh. NMI received for unknown reason b1 on CPU 0 kernel: Dazed and confused, but trying to continue. Kernel: seems to be a problem, likely on the PCI Bus
I'm not able to reproduce the problem every time i want, but, sometimes happens when i activate the snow effect combined with the cube effect, using kwin. My computer and OS specifications are: Pentium IV HT(disabled) Nvidia Geforce 8400gs 2 Gb Ram DDR2 (1xGB, 2x512) Hard Drives: 2x80GB Using Fedora 12, KDE 4.4.1, with Nvidia privative drivers, nouveau disabled

My laptop has only 2GB of RAM so I don't think I need the PAE kernel, also there are some drivers that I want to install, they were built for non-PAE kernel.
So far I read that I have to change the :
/etc/sysconfig/kernel
---------
# UPDATEDEFAULT specifies if new-kernel-pkg should make
# new kernels the default
UPDATEDEFAULT=yes

From F12 to F13. Is there anything I should remove before updating? I have few programs isntalled from source/binary installers in /usr for example. Would it cause problems?
And is there any chance to be able to switch from a 32 bit kernel to 64 bit kernel during the update? The hardware is capable of this.

I used Backtrack 5 and Fedora, basically I'm trying to install my wireless card but I don't have these installed to make && sudo. I burned the iso images for backtrack and fedora and booted my computer from them but can't figure out how to install kernel-devel on backtrack for example. I dled yum onto my flash drive but can't figure out how to install it.
