Public bug reported:
Hardware:
- Apple MacBookAir6,2
- Intel Haswell HD Graphics 5000 (i915)
Software:
- Ubuntu 26.10
- Mesa 26.0.3
- Kernel 7.0.0-27 and 7.0.0-28 affected
- Currently testing kernel 7.0.0-14
Problem:
The system randomly hard freezes. The display remains unchanged with no
graphical corruption, but the keyboard and mouse become completely unresponsive
and only a hard power-off recovers the system.
The freezes are not tied to any particular application. One crash
happened while running Papers, but other freezes have occurred during
normal desktop use.
The previous boot journal contains the following kernel oops:
BUG: unable to handle page fault
Call trace:
kfree()
eb_relocate_parse_slow [i915]
i915_gem_do_execbuffer [i915]
i915_gem_execbuffer2_ioctl [i915]
The same MacBook Air hardware is completely stable under macOS
(including Big Sur), suggesting this is a Linux kernel regression rather
than a hardware fault.
The issue has occurred multiple times on kernels 7.0.0-27 and 7.0.0-28.
I am now testing kernel 7.0.0-14 to determine whether the regression was
introduced after that version.
