Title:
Suspend not working intermittently when closing lid on ThinkPad T420s
Status in linux package in Ubuntu:
Invalid
Bug description:
Suspend doesn't work when closing the lid on my ThinkPad T420s. There
is no issue with 14.10 or 14.04. Kernel 4.0 do not help.
dmesg when closing/opening with kernel "Linux alex-ThinkPad-T420s 3.19.0-7-generic #7-Ubuntu SMP Thu Feb 26 20:19:34 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux":
[ 94.842668] systemd-logind[1262]: Lid closed.
[ 102.468204] systemd-logind[1262]: Lid opened.
[ 102.468661] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment
[ 124.075694] systemd-logind[1262]: Removed session c1.
The i915 seems to be unrelated: it appears after the lid is opened
again, and "pci=noacpi" makes it disappear but the bug stays.
I managed to got it to work, after playing with the e1000e driver as suggested on https://bbs.archlinux.org/viewtopic.php?pid=1414261#p1414261, but with a dubious and inconsistent state:
- doing nothing, e1000e loaded, it never goes to suspend when I close the lid (tried 5 times)
- removing e1000e, goes to suspend when I close the lid
- doing nothing, e1000e removed, it again cannot go to suspend when I close the lid
- loading e1000e, goes to suspend when I close the lid
WORKAROUND: Manually suspend.
