t61 hibernate dmesg
Comment 2 DongpoLiu 2009-06-18 05:37:48 UTC 
BTW, this issue happens when T61 is set in a dock, while no such issue if T61 is out of a dock.
Comment 3 DongpoLiu 2009-07-03 02:39:14 UTC

Comment 4 Matthew Garrett 2009-07-10 12:33:51 UTC 
Does anything actually stop working as a result?
Comment 5 DongpoLiu 2009-07-13 01:50:08 UTC 
I did a regression test at RHEL 5.4 Snap1 OS with 2.6.18-156.el5 x86_64 kernel. 
run "pm-hibernate", I can see T61 with Dock just blanks screen to enter hibernante state, but soon it automatically return to normal OS. 
dmesg is attached.

dmesg of t61 with RHEL 5.4 Snap1 x86_64 OS
Comment 7 Matthew Garrett 2009-07-13 01:58:38 UTC 
You have no swap device in the -156 test. See "swsusp: Cannot find swap device, try swapon -a" from the dmesg. What is the actual reported bug here?
Comment 8 DongpoLiu 2009-07-13 06:09:35 UTC 
I reinstalled RHEL 5.4 Snap1 OS with swap enabled, pm-hibernate can go now.

with Dock, above issue can be reproduced, while Ethernet/Audio/Graphics are OK,it seems nothings stopped.
Comment 9 DongpoLiu 2009-08-19 05:59:54 UTC 
re-test at 2.6.18-158.el5 kernel:
with dock, pm-hibernate goes OK and Ethernet/Audio/Graphics are OK after wake it up.
Comment 10 Matthew Garrett 2009-09-02 17:30:41 UTC 
So this bug can be closed now?
Comment 11 DongpoLiu 2009-09-03 01:05:56 UTC 
yes,pls close it.
