Imre, any advice here?

HI, Are you able to test our latest tip: https://cgit.freedesktop.org/drm-tip? Or does this help, Chris, Mika?
Ping reporter, can you try drm-tip?
(In reply to Francesco Balestrieri from comment #12) > Ping reporter, can you try drm-tip? I'm afraid but at the moment I can't try drm-tip. Maybe I can try this out when I have more time.

Knut, Sorry for the delay... Couldn't find gpu hang from dmesg. I see errors related FIFO underruns in dmesg. Can you please attach dmesg with kernel parameters drm.debug=0x1e log_buf_len=4M from boot. Can you please do that from latest drm-tip. This would be really helpful for investigating this issue.
Knut, any updates here? If there is no GPU hang with recent/latest drm-tip, I would like to close this and not to include FIFO underrun errors in to this bug, as this bug is originally for GPU hang.
Is there a debian rootfs / livecd I can use to check this. Trying drm-tip on the system is too much effort, don't have the time to try.
Setting to medium priority until we have more details. Is the problem still about GPU hangs or something else?
Knut, Any updates here? If you don't notice ahang with recent kernels, I can close this bug. Regarding FIFO underrun errors we have few open issues. Before creating a bug ensure there are no open issues.
No feedback from many months, closing as resolved works for me. Please re-open if issue persists with latest drm-tip https://cgit.freedesktop.org/drm-tip and send dmesg from boot with kernel parameters drm.debug=0x1e log_buf_len=4M?
