Package: rasdaemon
Version: 0.6.7-1+b1
Severity: important
Tags: upstream

With linux-image-6.0.0-2-amd64 rasdaemon causes a kernel oops with a signature 
similar to this:
 BUG: kernel NULL pointer dereference, address: 00000000000001c8
 #PF: supervisor write access in kernel mode
 #PF: error_code(0x0002) - not-present page
 PGD 0 P4D 0 
 Oops: 0002 [#1] PREEMPT SMP NOPTI
 CPU: 11 PID: 1227 Comm: rasdaemon Tainted: P           OE      6.0.0-2-amd64 
#1  Debian 6.0.6-2
 RIP: 0010:ring_buffer_wake_waiters+0x1c/0xa0

for a discussion of the bug (easiest to start from the bottom). It seems that
on systems which allow more cpus than are initialized[1], rasdaemon will attempt
to poll non-existent cpus which causes a kernel oops. The fix for this
reportedly causes rasdaemon to segfault which will likely require a fix there
as well.

A workaround for systems experiencing the oops with linux-image-6.0.0-2 is to
disable rasdaemon.

[1] On my system, dmesg reports
smpboot: Allowing 32 CPUs, 16 hotplug CPUs
for a system with 8 cores/16 threads
