Subject: RE: mei: cancel stall timers in mei_reset

Hi,

>Looks like there is a hiccup in scheduling during resume and timer work is kicked before its time and starts unnecessary  the reset flow.
>Can you check  that the device is in good state (<debugfs>/mei/devastate , it should be ENABLED).

Yes, /sys/kernel/debug/mei/devstate contains "ENABLED" (checked on kernel 3.10.15 I built with schedule_...() commented out).

>We will work on some solution. 

Thanks!

Regards,
Eugene
