This is a NULL-pointer dereference in mesa's nouveau driver that causes crashes in content processes. The vast majority of the crashes are coming from Debian 9 and older with older Ubuntu LTS ranking somewhat below that. More recent versions of mesa seem unaffected. I will file a bug in Debian's tracker and link it back here.

It seems that reporting a bug to Debian w/o having Debian installed is tricky business. I'll let this lie until I have some spare time to install Debian in a VM.

:marcia, could you have a look please?

This is not something we can fix ourselves but we should try and make sure that it's fixed upstream so setting to P3.

Crash Signature: [@ nv30_fp_state_bind] → [@ nv30_fp_state_bind] [@ nv50_validate_tic ]

On Nightly this crash signature has been spiking 10x in the last days, the crashes started to spike after March 27

The second signature is being handled in bug 1626898 so I'm removing it from here since it's a different crash. After that lands the driver responsible for this will be blocked so this should go away too.
