I'd prefer to try and fix these bugs. If need be, we can revert in the beta branch.

This issue should either be be a Beta blocker, or the offending change should be reverted.

It's a one or two line fix, so unless there are more bugs like it in other drivers, it won't delay the beta at all. I'll make the fix later today.

The problem is here: http://xref.plausible.coop/source/xref/haiku/src/add-ons/kernel/drivers/graphics/intel_extreme/intel_extreme.cpp#357
In addition to B_KERNEL_READ_AREA | B_KERNEL_WRITE_AREA, there should also be | B_USER_CLONEABLE_AREA.

bbjimmy reports this as fixed, but he says there is a different panic relating to acpi_task.

This doesn't seem to make a lot of sense. There are only 2 areas cloned in that function, they are not cloned conditionally, and if it works on one intel_extreme system (as BlueSky says it does) it should work everywhere. Are you sure you are really on 52197?

I am as sure as I can be, I just attatched the syslog from the boot attempt.

KERN: loaded driver /boot/home/config/non-packaged/add-ons/kernel/drivers/dev/graphics/intel_extreme
It seems you have an old intel_extreme driver in non-packaged.
Most likely because of https://git.haiku-os.org/haiku/commit/?id=023a547dc6981f10bb8437cfba7fcaa3fe3b0d01
I would suggest reverting this change for the beta, it is too dangerous to do this close to a release. We can do it after the beta is out.
