Title:
System Freeze with "Resetting rcs0 for hang on rcs0"
Status in linux package in Ubuntu:
Confirmed
Bug description:
* The problem started with linux kernel 5.3.0-46
* When the screen (GPU?) is used intensively, I can hear coil noise from my
laptop (Dell XPS 13)
and then the whole system will freeze during 5-6 seconds. During freeze I can
move the mouse cursor, but nothing else is responding. During freeze, the noise
stops. Then the systems comes back to normal for a few seconds (randomly from
10sec to 1 minute), and then the freeze repeats again and again.
* According to my experience, I would strongly bet that the coil noise
is due to graphics.
* The hang is reported in the dmesg log:
[ 64.369654] i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0
[ 64.370664] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 162.345195] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 192.360856] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 206.312567] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 230.343937] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[ 254.343235] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
* I have a small demo which uses the GPU intensively (via the SDL library)
and I can repeat the freeze easily by running it.
* The problem does *not* occur with 5.3.0-45-generic (no noise, no
freeze)
