dmesg captured from terminal using ssh.
I was running modified version of mesa when I got GPU hang. (My changes may have broken state)
But effects of gpu hang were fatal:
-dmesg has message that radeon was trying to reset GPU
-ring test failed so reset failed
-dmesg is spammed with messages that scheduling IB failed
-whole computer is unresponsive localy
-open ssh connection works for only few commands (luckily dmesg did work)
-It seems like no disk access can happen after hang
-No new ssh connection are possible
-Old ssh connection did freeze soon so not much useful info there
After reboot logs didn't include any info from hang or after it.
I have seen before similar hang with M9+ card but no ssh connected then so no debug info.
