I have installed FC5 on my system and it works for couple of days and suddenly it stops responding. Rebooting is the only option to use the system again.

Linux dev 2.6.15-1.2054_FC5smp #1 SMP Tue Mar 14 16:05:46 EST 2006 i686 i686 i386 GNU/Linux

Here is the message I see in the system log

Apr 29 02:58:16 dev kernel: ata1: command 0x35 timeout, stat 0x50 host_stat 0x4
Apr 29 02:58:16 dev kernel: ata2: command 0x35 timeout, stat 0x50 host_stat 0x4

Apr 29 03:00:16 dev kernel: ata2: command 0x35 timeout, stat 0x50 host_stat 0x4

Is it an known issue with FC5 (2.6.15-1.2054_FC5smp)?

Any help is appreciated.

thanks,
durai.

Welcome to LQ

Update your system to the latest kernel 2.6.16-1.2096_FC5smp. This might work.

Post your complete hardware details.

Before you do all that, try the simple fix first: Open your computer case (with the power off, of course), unplug each disk drive cable, at each end, one end at a time, and plug it back in.

It is often the case that a little oxidation can build up on the connectors, and the "scraping" done by removing and replacing the plug will "clean" the contacts. The problem you describe is typical of a "broken" connection.

Here is my hardware configuration. I bought two new boxes and both of them having the same problem. I installed the Fedora Core 5 image on both of them. I am currently updating my system with latest packages. Will keep you posted on the result.

I have two sata disks (160G each) in each system. They are configured as RAID1
(hardware RAID1).

Thanks for your help. I would also going to try PTrenholme suggestion once the update is done.

I just discovered that some ATA timeout problems can result from using a BIOS setting for "enhanced mode" rather than "compatibility mode." You might want to check your BIOS and see if it makes a difference. (Of course, that was with parallel ATA drives, not serial, so it might not apply.)

OK, I get same behavior, but I don't think it has to do with sata. I decided this must mean my harddrive was going bad, and bought a IDE drive to replace it. I just got the lockup w/o getting this error message. Here's another guy with same problem (crappy site is not allowing me to post url,
its at redhat.com under archives/rhl-list/2006-April/msg04323.html).


I have a Athlon-64 X2 system . . . No idea yet what is going wrong, but I'm not sure the lockup is caused by the drive . . .

OK, Filippos (the guy who had the same problem on the red hat site) provided the solution: edit your /boot/grub/grub.conf file, and add "noapic" (without the quotes) to your kernel line. I did it, no lockup for whole day . . .
