CentOS 5 :: Custom Kernel For Enable Write Barriers With Xfs And Lvm2,worth?
Dec 7, 2010I have read that when using xfs with lvm2, prior to kernel 2.6.29 write barriers are by deffault disabled.As i want to migrate /home to xfs (and create a external partition to hold some data in xfs too) i was thinking in compile a custom kernel 2.6.30 or higher from [URL].I have read the wiki, all the warnings , and that for compile a kernel.org kernel you should use the Linux Kernel in a Nutshel guide/book. But i don't really know if would worth do that only to have write barrier support , more when in one month i will buy a ups to be sure i can shutdown the pc well if the power goes out.Should i enable write barriers on xfs with lvm2 ,although going to have a ups ?

View 4 Replies View RelatedProgramming :: Macos Does Not Have Barrier Functions?
May 9, 2010The pthreads library on macos does not have barrier functions (pthread_barrier_t ....). Is there a way to get around this? I know I can do :
#ifdef __APPLE__
pthread_barrier_t ...
#else
my_barrier ...
#endif
But I would like to avoid this approach as there are a lot of places in my program where I would have to make this change. Can I perhaps rebuild the pthreads library on macos without affecting other apps ?

Jan 24, 2009I've been trying to get my palm TX to sync with kubuntu 8.10. Quickly after I place the palm on the cradle I get a warning msg that I've attached below. I did follow some directions at one point where it required me to install visor. It had sync'd a few times, but then it started giving me these errors. Eventually I tried to delete the device, etc.
The msg:
Failed to connect using device 'Cradle', on port 'usb:'.
Check your confirguration, as you requested new-style libusb

You may need to select a 'ttyUSB...' device

General :: Kernel Panic On Boot - Authentication Process Failed
Feb 22, 2011I got home today to find that my KDE login screen would not let me log in. It said the authentication process failed or something and I needed to terminate the screen lock process manually. So I go over to another virtual terminal and try to log in. As soon as I enter my user name, a bunch of errors come up and I am unable to log in. "This can't be good" I think to myself, and reboot.
I am greeted by this error upon booting:
The error says that it says it cannot find /sbin/init. I loaded up a Ubuntu live CD and verified that /sbin/init is indeed present and all my other files still seem to be there. I tried booting into arch fallback on grub but that didn't work either. Midway through the day I SSHed my desktop from my phone and started it doing an upgrade. I was able to login.

OpenSUSE :: Sync Pim Data With Palm Treo 680 Via Bluetooth - Jpilot Sync Suddenly Broken
Oct 24, 2010I use jpilot on opensuse 11.3 64bit to sync pim data with my Palm Treo 680 via bluetooth. This worked fine until today. Now I get the following error message when I try to sync: Syncing on device bt: Press the HotSync button now dlp_ReadSysInfo error Exiting with status YNC_ERROR_PI_CONNECT Finished.
The last successfull sync was on the 20th October and today is the 24th October. I did not change any settings in jpilot or on my palm device. So I guess there must have been an update of opensuse which causes this error. But I do not now how to look up the updates during this period or how to undo them. Was there an update between the 20th and the 24th Oktober, which might affect either jpilot or bluetooth functionality?
Ubuntu One :: Sync Chewing Up CPU Cycles - Using From 50-80% Long After Any Sync-able Files
Sep 10, 2010I've got Ubuntu One syncing a single 25MB folder on 4 computers. On one of these computers, the ubuntuone-syncdaemon process constantly pegs the CPU, using from 50-80% long after any sync-able files have been modified and successfully synced. The process is only using 8.9MB of RAM.

Ubuntu Multimedia :: How To Sync Audio On Already Badly Out Of Sync Video?
Jul 9, 2011Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps, the parameter is the maximum samples per second by which the audio is changed. -async 1 is a special case where only the start of the audio stream is corrected without any later correction.Searching the net makes one believe that this command is just some sort of magic.People just put it in the line and it just works. Isn't that nice?
It says nothing about how to change the TIME the audio starts syncing. Like do I want it to start 5 seconds delayed? Or what about 5 seconds sooner?What if the audio gets more out of sync as the video goes on? Can I slip it a little at a time? What? No magic?No one mentions a file that already has badly synced audio.So what -async 1 really does is simply start the audio at the beginning of the file. LIKE AS IF THAT ISN'T STANDARD PROCEDURE?So what is the exact solution to syncing a messed up video? And why can't it just do the proper "timestamp" sync in the first place?No docs, no info and you are left out in the cold.
Fedora Installation :: Boot Any Current Kernel Without The Nolapic Flag On ICH8-based Intel T7300 Systems?
Jun 16, 2009Is there a way to boot any current kernel without the nolapic flag on ICH8-based intel T7300 systems? This system works fine with the last 2.26 kernel from FC8, but due to EOL of the security updates I tried to install FC11 and FC10. The first sign of trouble is that their installation only works with acpi=off or nolapic options. As those options disable either fan-control or the second cpu-core I consider them undesirable. Is there a recent correctly working kernel available? Or do I have to downgrade to a distribution that uses a 2.26 kernel?

View 2 Replies View RelatedGeneral :: Audio - Disabling Built-in Speaker?
Jan 28, 2010My workstation has a built-in speaker that, surprisingly, plays audio very well. I also have external speakers hooked up to the audio out jack which are easier to hear. Unfortunately, when I try to play some audio material, sound comes out of both the external speakers and the built-in speaker on the workstation.
I'd like to disable the speaker inside the machine, and just plug in head-phones to the external speaker so I can listen to training material at work without bothering my office mate. I'm not sure how to do this in Linux (Suse Enterprise Desktop 11). Fiddling around with the Gnome audio tools doesn't list two different audio devices on the machine.
From what I can tell, sound is played through the ALSA system. I looked in my home directory and there is no .asoundrc controlling configuration.
I should also add that I check in the BIOS for a way to disable the built-in speaker, but I could not find such a setting.
