Not sure whether I should open new report. I think I've been hit by the same
bug with similar characteristics.
I started to notice short (second, mostly less) freezes with 5.3 kernel (don't
know the exact version, since I got it from Debian unstable it surely wasn't
the initial 5.3.0). With 5.2 kernel everything was fine. I notice freezes only
in Firefox and Thunderbird.
I get the same dmesg output (mostly Resetting rcs0 for hang on rcs0).
/sys/class/drm/card0/error got generated I think when I tried to close message
window in Thunderbird. If you want I can upload my /sys/class/drm/card0/error.
Not every freeze in Firefox/Thunderbird generates "Resetting..." message to
Firefox, so I'm not 100% sure that these are related actually. I connected
these things today, so I start monitoring.
I haven't compiled running kernel from source in a years, so I can't currently
do it. If you point me to good instructions, I can try to git-bisect this.
