[Intel-gfx] i915: boot/load regression since Linux v5.7-rc1 on Iris Pro (Crystal Well)

[Intel-gfx] i915: boot/load regression since Linux v5.7-rc1 on Iris Pro (Crystal Well)

[Peter Vollmer]

Hi,

since kernel v5.7-rc1 my graphical output hangs on boot or if the i915
module is blacklisted on modprobe.
I've already found and extended a bugzilla
https://bugzilla.kernel.org/show_bug.cgi?id=208737

But sadly there has been little reaction so I would appreciate any
help in further debugging or better yet resolving this issue.

Thanks in advance

Peter Vollmer

Sorry, nobody in the team looks at kernel.org bugzilla except once in a
blue moon to close bugs and tell people to report bugs at fdo gitlab
[1].

BR,
Jani.

Hi Jani,

there is also already a bug report at
https://gitlab.freedesktop.org/drm/intel/-/issues/2381 but it also seems to
get not much attention.
Ville Syrjälä from Intel provided a workaround and mentioned the issue was
encountered before, but has never been fixed.
It would be great if someone from Intel would be investigating this bug
that renders the affected machines virtually unusable and I guess all
affected users who chimed in are willing to provide any information needed
to find the root cause of this issue.
Looking forward to hearing from you or your team!

Best regards,
Peter Ganzhorn
