I've got an old tablet PC that panics on boot with ACPI GPE storms. It boots just fine with
acpi=off in the kernel arguments, however I've never been able to get the Intel i915 accelerated graphics working (Intel 855GM chipset).
I have no idea why the two should be related but I've come across a few reports of
i915 being dependent on
- The i915 drm module has an indirect dependency on ACPI | Red Hat Bugzilla
- Why Intel i915 driver depends on button module | Debian User Forums
How can I verify this dependency and is there any way to get accelerated graphics with my busted ACPI?
