Subject: kernel BUG at kernel/locking/rtmutex.c:1059
Date: Wed, 30 Aug 2017 23:25:53 +0200 [thread overview]
Message-ID: <86val4928u.fsf@gaheris.avalon.lan> (raw)
Hi,
As of v4.11.12-rt8 my laptop runs into trouble booting up, throwing a
kernel BUG when starting up bluetooth. Bisecting *seems* to lead back to
commit 6fb87cb1181786dc88432c6c6093a02a897e5789, 'Add the hotplug rework
including all its side stories'.
The issue persists up to v4.11.12-rt10
Stacktrace:
