We have a new machine here that we are trying to use for CentOS as a base for our primary application. Although I do not have direct access to the physical machine, I have begun looking into it remotely (via ssh) to see why we are getting the following errors periodically:

/var/log/messages.1-Nov 1 18:19:00 Centos5 kernel: hda: status timeout: status=0xd0 { Busy } /var/log/messages.1:Nov 1 18:19:00 Centos5 kernel: ide: failed opcode was: unknown /var/log/messages.1-Nov 1 18:19:00 Centos5 kernel: hda: no DRQ after issuing MULTWRITE_EXT /var/log/messages.1-Nov 1 18:19:00 Centos5 kernel: ide0: reset: success

This happened 12 times (at least) in the last four days, and it (reportedly) does not occur if FC9 is booted on that machine.

The machine is configured as follows:

Pentium Core 2 Duo at 3.4GHz, 1GB RAM Intel m/b, not sure exactly which one, but here's what lspci shows:

The disk is a Seagate ST3250310NS (250GB) with an 8G /boot, 65G / and 160G /usr, with 2 2G swap partitions in the extended partition (!).

(Seagate - I smell trouble, but, as I said, FC9 doesn't do this at all.)

uname -a returns Linux Centos5.2SATAMaster 2.6.18-92.1.13.el5 #1 SMP Wed Sep 24 19:33:52 EDT 2008 i686 i686 i386 GNU/Linux.

I've run the smartctl utility, and it shows no errors.

What am I missing? Is it odd to have two SATA controllers for a single disk drive, or is that at all relevant?

Thanks.
