journal commit i/o errors

[Mike Iglesias]

My desktop system is a MSI K8T Master2-FAR w/2 Opteron CPUs.  This system has 
been running various releases of i386 Fedora (not x86_64 due to various 32 vs 
64 bit issues), starting at Fedora Core 2, upgrading to FC3, FC4, FC5, FC6. 
It had no real issues with any of those releases of Fedora.

During the Christmas break I did a fresh install of Fedora 8 with all the 
current patches.  The system ran fine for a couple of weeks on kernel 
2.6.23.9-85.fc8.  It then started to get this error

  kernel: journal commit I/O error

The errors don't have any kind of pattern - the system may run for less than 
24 hours or for several days before the error happens.

Figuring the hard drive may be going, I replaced it and moved the Lite-on DVD 
drive to the other IDE bus, using new IDE cables for both drives.  The 
problems continued to happen, so I tried disconnecting the DVD drive in case 
it might be causing some kind of issue that was causing the journal commit 
errors.  I still got the errors, so I went back to the kernel that was 
installed by the F8 install, 2.6.23.1-42.fc8.  The system ran for a week with 
no problems with that kernel.

I've also tried the latest F8 kernel, 2.6.23.14-107.fc8, and got a journal 
commit error there too (in less that 24 hours), so I'm back on the 
2.6.23.1-42.fc8 kernel for now.

Does anyone have any ideas on how I can track this issue down?  From what I 
can tell, it's either a motherboard problem or a kernel bug/issue, but there 
may be something I'm overlooking that might be causing this.


Thanks,
