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?
