Please share the dmesg log, and whatâ??s the chip are you using ?

I am interested on this. Currently when a "ring X stalled for more than N sec" happens it usually goes into the gpu reset routine. Does it always cause the vram to be lost ? Could you explain what happens if the vram remains lost ? I am asking this because I experienced some recurrent gpu reset that are marked succeeded from the log but fail in the "resume" step. I would not be interested in this if it would always leave a chance to the user to cleanly reboot the machine. The issue is that it can require a hard reboot without kernel panic and without keeping the keyboard responding to magic keys. Are those patches trying to address this issue ? Note that here "issue" is not referring to the root cause of a ring X stalled and it is also not referring to why "resume" step fails.
