Summary: SATA drive fails to wake up on resume from suspend-to-
RAM
Kernel Version: 2.6.17.1
Status: NEW
Severity: normal
Owner: jgarzik at pobox.com
Submitter: rl03 at gentoo.org
Most recent kernel where this bug did not occur: N/A
Distribution: Gentoo Linux
Hardware Environment: Lenovo T60p laptop (dual Pentium-M), SATA controller in
AHCI mode: SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) Serial
ATA Storage Controller AHCI (rev 02) (prog-if 01 [AHCI 1.0])
Software Environment: gcc-4.1.1, glibc-2.4
Problem Description:
On wake-up from suspend-to-RAM hard drive in SATA mode does not come back to
life (e.g, ls hangs indefinitely). When SATA mode is set to "Compatibility"
instead of "AHCI" in BIOS, hard drive resumes fine. Applying a patch from FC5
[1] fixes the issue. Reproduced with vanilla 2.6.17.1 and suspend2-2.2.6.
[1] http://cvs.fedora.redhat.com/viewcvs/rpms/kernel/FC-5/linux-2.6-sata-ahci-
suspend.patch
Steps to reproduce: suspend to RAM, wake up, hard drive does not wake up.
This appears to be different from the issue in bug #6714.
