| |
Hi,
having the "mei" driver loaded, which happened automatically on my ThinkPad X200s, successfully prevents any suspend efforts:
[39736.728116] pci_pm_suspend(): mei_pci_suspend+0x0/0xc0 [mei] returns 9999
The code has not changed since 3.0-rc2, so I did not try compiling latest git.
Jiri Slaby hinted that this code in drivers/staging/mei/wd.c is to blame:
169 ret = wait_event_interruptible_timeout(dev->wait_stop_wd, 170 dev->wd_stopped, 10 * HZ);
I am, however, not familiar enough with timers and stuff to immediately spot the problem.
Removing the module before suspend is a workaround.
This could be considered a regression, as suspend worked very well before this driver was introduced :-)
Best regards,
