Re: PROBLEM: i915 causes complete desktop freezes in 4.15-rc5

[Alexandru Chirvasitu]

Compiled a couple of kernels with kasan enabled. I don't yet have a
crash, but on the system that has been crashing I have the following
kasan distress signals on bootup (dmesg attached):

[    0.027923] Disabling lock debugging due to kernel taint





I'll follow up on the crashes when they happen, but I thought this
might be of some use.

Incidentally, I've compiled two kernels with kasan on: one using the
bad system's config (with make oldconfig), and one using the one on
the system that doesn't crash on the same machine.

The latter does *not* spit out the trace in dmesg (regardless of which
system I boot it on), while the former only complains on the bad
system (boots fine on the good OS).

So it must be specific to the kernel configuration + kernel
parameters, but I don't know how. I haven't mesed with the kernel
parameters myself: they are whatever the two respective GRUB
installations came with by default on the two systems.

I can attach whatever's needed and try out whatever you think might be
helpful, but I figured I'd keep the message light with just the kasan
trace dmesg attachment.
