Most recent kernel where this bug did not occur: 2.6.15 Distribution: Fedora Core Devel (Rawhide) Hardware Environment: AMD64 + SATA, nforce4 chipset + sil chipset, 2 GiB mem Software Environment: raid 1 + lvm Problem Description: Booting in any recent davej kernel results in lots of system errors (md, sata) and quick filesystem corruption Some examples : ata5: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 ata5: status=0x51 { DriveReady SeekComplete Error } ata5: error=0x04 { DriveStatusError } sd 4:0:0:0: SCSI error: return code = 0x8000002 sda: Current: sense key: Medium Error Additional sense: Unrecovered read error - auto reallocate failed end_request: I/O error, dev sda, sector 4192831 (no idea if the problem is in the SATA layer or somewhere deeper) More material (logs, lspci...) available in: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=177951
I'm a fool - retested yesterday with latest davej kernel (some git versions later), crashed again, spend some hours cleaning up the system and worrying about damage Thanksfully 2.6.15 "only" got a scsi memleak, so if I reboot it often enough it's working fine
Smart info was attached to the Fedora bug (basically smart thinks the drives are fine)
2.6.15-1.1872_FC5 (2.6.16-rc1-git4) patched to disable FUA (as suggested by Tejun Heo there : http://marc.theaimsgroup.com/?l=linux-ide&m=113825474609128) boots fine
Closing as workaround for this firmware was merged by Linus
