Description Adrien Bustany 2007-11-22 04:29:55 EST
Description of problem:
If using ahci instead of ata_piix for controlling the hard disk, a sony vaio sz6
(ICH8 controller) will not resume from S2RAM. Everything wakes up correctly
except the disk, so I can run recent commands (which are still in the RAM) but
everything else gives IO error. The disk spins though.

Version-Release number of selected component (if applicable):
Linux #1 SMP Thu Nov 8 22:14:09 EST 2007 x86_64 x86_64 x86_64

How reproducible:
Switch the HDD from ata to native sata, suspend to ram, try to resume

Actual results:
Everything wakes up (video mode is OK, eveything that was in ram works), but any
access to the disk fails. The disk spins up though.

Expected results:
Access to disk should work

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.


I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few weeks if there is no additional information lodged.

this is now an old bug, and I reverted my bios to ide mode. Actually, switching
is quite painful cause I have to edit my bios with an hex editor. I close this
bug for now...
