Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting
for once, to make this easily accessible to everyone.

Nick, what's the status/was there any progress? Did you do what Mario
suggested and file a nouveau bug?

I ask, as I still have this on my list of regressions and it seems there
was no progress in three+ weeks now.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

If I did something stupid, please tell me, as explained on that page.

#regzbot backburner: slow progress, likely just affects one machine
