Subject: Bug: d0e936adbd22 crashes at boot
Date: Fri, 3 Sep 2021 07:36:27 -0600 [thread overview]
Message-ID: <942f4041-e4e7-1b08-3301-008ab37ff5b8@kernel.dk> (raw)
Hi,
Booting Linus's tree causes a crash on my laptop, an x1 gen9. This was a bit
difficult to pin down as it crashes before the display is up, but I managed
to narrow it down to:
commit d0e936adbd2250cb03f2e840c6651d18edc22ace
Author: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
Date: Thu Aug 19 19:40:06 2021 -0700
cpufreq: intel_pstate: Process HWP Guaranteed change notification
which crashes with a NULL pointer deref in notify_hwp_interrupt() ->
queue_delayed_work_on().
Reverting this change makes the laptop boot fine again.
