I've built my own kernel and now boot.preload complains about the missing preloadtrace.ko kernel module.

Where can one find the source for this module?

OpenSUSE Install :: /dev Full Due To Preloadtrace.log?

Nov 23, 2010

Just after boot of my opensuse 11.2, the /dev is less than 10% full. But, as time runs, it becomes full, leading to problems. I have searched for the reason, and find an ever growing file, named preloadtrace.log.May I rotate this log as other ones with webmin (and should I use special commands to do it), or is it possible to avoid the creation (or the filling) of this file ?

OpenSUSE Install :: Apparmor Module Does Not Load On Kernel-rt?

Aug 6, 2010

I have just reinstalled OS 11.2 but this time the 64bit system variant. I installed the real-time kernel and saw that the apparmor module reported an error and wasn't loaded. I have never looked into apparmor and only knows it has something to do with security, and thus I wonder if it is important to do something with this issue? I plan to use the kernel-rt and have more or less always used a variant of this kernel flavour, often self built. Though I can not recall having seen that error before and I have not used a 64bit system before

OpenSUSE Install :: 11.2 (64bit) - Kernel Module Will Not Start In Vbox

Jan 23, 2010

I Just loaded 11.2 64 bit, initially the kernel was "default", however, after I installed my Nvidia drivers it changed to desktop, I'm not sure I understand? In GRUB my screen lists it as desktop. Is "default" somewhere? Was it replaced? Things seem to be working alright in most cases although I'm having inordinate problems with "virtual Box" and Vmware server. In Vbox the kernel module won't start.

OpenSUSE Install :: Kernel Upgrade On 11.1 - Cannot Find Module After Reboot

Nov 10, 2010

I've upgraded kernel to on openSUSE 11.1. Before I tried to upgrade to where I encountered the same issue. After reboot it can not find the modules for which puzzled me to no end. Now I have found that the /boot which is on separate partition of ext2 type is not mounted. The mount command does not recognize ext2 and xfs anymore.

Clearly the initrd does not have the right modules. Since this is standard zypper up process I would expect this to work without issues since it has worked until the kernel without issues. Has something changed with the last 2 kernel versions that requires some extra actions from me and if so what do I have to do.

OpenSUSE Install :: Disable Preload For Certain Files / Program?

Apr 18, 2010

Is there a way to disable preload for a given process and/or a set of files? I'm having an issue with MLDonkey, which I configured to run as a service. Apparently, preload is trying to pre-load the temporary files lying under MLDonkey working directory (which are huge), and tis is causing a massive slowdown when booting

Fedora :: Kernel - VirtualBox - Missing Module

Jun 16, 2011

I generally check what updates are being installed. This time sadly I didn't and again this kernel had one missing module. VirtualBox-OSE stopped working. It had been working fine with other upgrades. No it's not a problem with dkms or other stuff. This kernel doesn't have vboxdrv module like other kernels...i verified it...


The version doesn't have vboxdrv module!....hence again I have to roll back to older kernel. So before blindly this message!

OpenSUSE :: SUSE Studio Preload ISO Refuses To Install (most Of The Time)?

Jul 18, 2011

Whenever I try to use a preload ISO from, it takes me about 5 tries to actually get it to install. I load it up in VirtualBox, and on the screen that warns "you are about to erase all data on /dev/sda, continue?", selecting "yes" will 80% of the time cause it to think you cancelled and waits 30 seconds before rebooting. Every now and then it decides to work, but sadly that's the exception and not the rule. If it makes any difference, the appliance I'm downloading is a custom one based on openSUSE 11.4 Minimal X with GNOME 3 installed on top of it.

OpenSUSE Install :: Disabling Preload To Avoid Very Long Startups?

May 10, 2011

For a number of openSUSE releases now, on a periodic basis (monthly, it seems?) both my laptop and my desktop take forever to start. During this time, the hard disk activity is going berserk. When inspecting this with "iotop", a process called "preload" or "start_preload" is hammering the disk, sometimes up to 10 minutes.

The irony is when you research "preload", you find mostly articles like "drastically speed up your Linux system with preload"- I sometimes think it has to do with running VMs on these machines and maybe it's trying to cache those large disk images? Pure speculation, but I can't seem to find any documentation on this.

Anyway, I did finally find a way to turn this thing off. WARNING: since I do not know exactly what preload does and whether your machine becomes unusable if you turn it off, please only follow these instructions at your own risk. Since preload seems to be a very low-level system/service, I did not want to risk uninstalling it. What I did instead was:

Yast2 - System Services (RunLevel)
Click the Expert Mode radio button
Scroll down to the boot.startpreload entry


Since I applied these steps, no long boot times with insane hard disk activity has occurred and I also have not noticed anything else complaining or not working with this service off.

OpenSUSE Install :: WPN111 Wireless Adapter And NETGEAR - Make The Module Load Automatically On Boot ?

Feb 14, 2011

Above adapter can be installed on v10.2 and 11.3 using ndiswrapper:-

1. Copy the 3 driver files from Windows:- like netwpn111.inf, WPN111.sys & ar5523.bin.
(Be carfeul about the exact names, because they have changed over time).

2. sudo ndiswrapper -i netwpn111.inf

3. sudo ndiswrapper -m

4. sudo modprobe ndiswrapper (the adapter should light up at this point and networks will be detected shortly after - see network manager). (Be careful of paths here - e.g. I had to use /sbin/modprobe - so 'whereis' may be necessary to find these commands).

2nd When I reboot, I need to run the modprobe command again. How do I make the module load automatically on boot? Also (and this is minor), can I bypass the KWallet, keyring thing? it seems silly to enter a password for the keyring and then click another password dialog, when I can just as easily enter the password for the network itself.

OpenSUSE Install :: Hal.dll Missing - Won't Boot Windows

Apr 25, 2011

I've seen a few other posts well over a year or 2 old about hal.dll missing, and windows not dual booting with grub, but all of those involved resizing or moving partitions. This install i just did of opensuse 11.4 only involved formatting over a Ubuntu partition which already ran and dual booted windows xp with no problem (no problems during ubuntu install) I am hesitant to try any previous fixes posted in the forums as my issue doesn't seem to have come about for the same reasons. I thought windows and linux were playing well these days, guess not.

Fedora Installation :: How And When To Load Kernel Module In Boot Up Process?

Jul 19, 2010

For a diskfull node (the OS installed in a disk), I can use the 'insmod' command to insert a kernel module into the kernel. And after the reboot, the module is still in the kernel. I have a question here: how, when and which kernel module will be loaded in the boot up process for a diskfull node?And for the diskless node, can I use the chroot or some other ways to install the kernel modules into ramdisk, so that kernel module can work when the diskless node boot up? I think it needs certain mechanism to load the kernel like the boot up of diskfull node.

General :: Pass Options To A Kernel Module Through The Boot Parameter?

I have an issue that is fixed by changing the lpfc driver to run using MSI interrupts. This is done by adding "options lpfc lpfc_use_msi=2" /etc/modprobe.conf.local file.

Is there a way to make this change using kernel boot parameters?

Software :: CUPS And Multiple USB Printers - Complains About Missing "filter"

Aug 3, 2011

For starters, I'll warn you that I installed linux on a pc for the first time yesterday. With the guidance of a pro, I'm running Ubuntu 11.04 desktop 32-bit with CUPS 1.4.6. I have three Samsung ML-2525 USB printers attached. They all three show up with lsusb:

Bus 001 Device 004: ID 04e8:3297 Samsung Electronics Co., Ltd
Bus 001 Device 003: ID 04e8:3297 Samsung Electronics Co., Ltd
Bus 001 Device 002: ID 04e8:3297 Samsung Electronics Co., Ltd

When I go into CUPS, it shows one. I've tried to add another via bash and I can't seem to get that to work either. All three were plugged in when CUPS was started, so I've ruled out that thing where it doesn't see new USB devices. I set up three printers in CUPS (via the web interface) and (no surprise!) they all print to the same printer. I then tried to force them to go to the right places by shutting down CUPS, modifying cups.conf to inculde "FileDevice yes", restarting CUPS and using lpadmin to change the uri's to their /dev/ filedevices. That doesn't work. You probably knew that already, didn't you!?


Then the jobs just sit in their queues forever. (I let it sit for 25 hours, they are still "processing").

OpenSUSE :: Kernel Module Development Barked

Feb 27, 2011

It is bad enough that the kernel gods have basically required that the whole kernel source tree be installed and configured to compile even a simple module but they have made it so a module compiled on one kernel will not work on any other.

To make the situation worse much of the configuration needed to successfully compile a module has been left out of open suse11.3. If you want to replicate the problems may I suggest you attempt to compile the usb-skeleton.c driver example code that is included with each kernel. If it is the intent of the linux community to limit driver development to the professionals then congratulations.

General :: Install New Module On Newly 2.6.35-rc5 Kernel?

Jul 16, 2010

Recently I was trying to look into vmware pvscsi modules for newly announced linux kernel 2.6.35-rc2. I compiled the kernel with option: make oldconfig where it asked me for various interactive options and all I did is Kept pressing the Enter ENTER key(Donno if that is the correct way to slect default ).The Kernel Compilation anyway went fine and I can see new kernel at grub screen, booted and it went fine.Now when I explored I found that nor the vmware_balloon and vmw_pvscsi modules are present which means I need to install these modules.I came to know that recently a new version of the vmware memory drivers being included through this page:


where you can see an entry like:


MODULE_AUTHOR("VMware, Inc.");
MODULE_DESCRIPTION("VMware Memory Control (Balloon) Driver");

Doesn't it mean that the new kernel has new driver version inboxed?Also, I tried to install modules through modprobe and insmod(seems that this doesnt work) but couldnt do that.

Is this a common problem? If not, I'll try to take a picture of the error so that you can see exactly what happened. I can still boot with kernel 2.6.34 like I could before the update.
