HDD DMA error and system hangs - FC3.

Sat Nov 27 18:14:16 UTC 2004

VJ, this is not the first time similar inquiries have appeared here, and
I encountered the same problem with a completely different hardware
setup.  I saw this happening on a SCSI raid w/caching controller.  I
discovered a work around by disabling cache writes to filesystem in the
mount.  Some of the newer ide/sata drives are coming with large caches
(~8meg), so it makes me wonder about a possible correlation there.
Maybe completely off target - just FYI...

	Nov 26 04:07:23 end_request: I/O error, dev hdh, sector 13071764

	I am running kernel "2.6.9-1.681_FC3" with "noapic nolapic
acpi=off".

	I ran Segate's own Seagate Tools for surface scan - No problem
found.
	I ran smartctl -t long /dev/hdh for SMART extensive test. No
problems there either.

	Any ideas???

	Regards from

	VJ
