Hardware Environment:
IBM ThinkPad Z60m

Software Environment:
Problem Description:

scsi subsystems dumps tons of errors, fs is remounted read-only, detailed description:

Comment 2 Arkadiusz Miskiewicz 2006-08-28 22:58:02 UTC 
It's fixed for me in recent kernels.
Comment 3 Martin Lorenz 2006-08-30 03:48:11 UTC 
not for me on a X60s with 2.8.18-rc5 and no other patches
Comment 4 Arkadiusz Miskiewicz 2006-08-30 03:53:11 UTC 
Z60m and X60s have different sata chipsets I guess. The one in z60m is ata_pix 
(no ahci available) and it works fine now.
Comment 5 Martin Lorenz 2006-08-30 04:11:22 UTC 
I got a 

SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) Serial ATA Storage
Controller AHCI (rev 02)
Comment 6 Martin Lorenz 2006-08-30 14:42:30 UTC 
great

forrest zhaos set of ahci patches does the trick for my SATA controller
it resumes nicely now that I have applied them to the 2.6.18-rc5 kernel
Comment 7 Martin Lorenz 2006-08-30 23:36:59 UTC 
Created attachment 8916 [details]
just for documentation: the patches I applied and mentioned above - tar.bz2
Comment 8 Martin Lorenz 2006-09-03 01:46:04 UTC 
Is there a chance that those patches will go into 2.6.18?
Comment 9 Pavel Machek 2006-09-27 01:46:49 UTC 
IIRC this patch series was deemed too intrusive for 2.6.18, but they should be
in 2.6.19-rc1 and 2.6.18-mm1.
Comment 10 Martin Lorenz 2006-09-27 01:59:22 UTC 
already found them in the current tree :-)
in snapshot -git6 they are included
Comment 11 Pavel Machek 2006-09-29 04:20:55 UTC 
Ok, so problem is fixed, right?
