HiNo exactly sure which patch did it - but when I'm now checking 3.8-rc5 kernel, I cannot use anymore this 'undock' command: echo 1 >/sys/devices/platform/dock.0/undock which works ok with 3.7 kernel - to properly undock my T61 before suspend. Dmesg shows this: [ 2657.087414] ACPI: \_SB_.PCI0.LPC_.EC__.BAT1: undocking [ 2658.613494] ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [ 2658.613508] ata4.00: ST_FIRST: !(DRQ|ERR|DF) [ 2658.613522] sr 3:0:0:0: CDB: [ 2658.613530] Get event status notification: 4a 01 00 00 10 00 00 00 08 00 [ 2658.613583] ata4.00: cmd a0/00:00:00:08:00/00:00:00:00:00/a0 tag 0 pio 16392 in res 00/00:00:00:00:00/00:00:00:00:00/00 Emask 0x2 (HSM violation) [ 2658.613670] ata4: soft resetting link [ 2658.766888] ata4.00: NODEV after polling detection [ 2658.766900] ata4.00: revalidation failed (errno=-2) Here is boot log attached, my HW is Lenovo T61, C2D
I've run 'bisect' and found out commit which has broken 'undock' support on my Lenovo: commit 8ab0ab2570cfc48303e545944f53690a6983a898 Author: Toshi Kani <[email protected]> Date: Tue Oct 23 01:30:26 2012 +0200 ACPI: dock: Remove redundant ACPI NS walk Combined two ACPI namespace walks, which look for dock stations and then bays separately, into a single walk. Signed-off-by: Toshi Kani <[email protected]> Reviewed-by: Yasuaki Ishimatsu <[email protected]> Signed-off-by: Rafael J. Wysocki <[email protected]> After doin plain revert of this commit undock 'support' is back - I've tested this with 3.9-rc1 (though on this kernel it seems wifi is again horribly broken for now) Any idea about proper fix here ?
