We don't have enough information. - What kernel version are you using? (uname -a) - What Mesa version are you using? (glxinfo | grep Mesa) - What were you doing at the time of the hang? Is it reproducible?

Sounds like it was a one-time occurrence. There's not much we can do to debug it if we can't reproduce it to begin with. Marking as NEEDINFO. Please reopen if you find a way to reproduce the hang or if it happens more frequently.
Dear Reporter, This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested. Thank you.
