Description (last modified by diver)

I've experienced three KDLs on 2 different PCs with Haiku nightly hrev55673 and Falkon running. In two of the cases, I wasn't near the computer at the time of the crash, so I literally didn't do anything to provoke the KDL. 

/var/log> grep -i "assert" /var/log/syslog.old 
KERN: PANIC: ASSERT FAILED (../haiku-git/src/system/kernel/locks/lock.cpp:931): lock->holder == waiter.thread->id
KERN: PANIC: ASSERT FAILED (../haiku-git/src/system/kernel/locks/lock.cpp:931): lock->holder == waiter.thread->id
KERN: PANIC: ASSERT FAILED (../haiku-git/src/system/kernel/locks/lock.cpp:931): lock->holder == waiter.thread->id

The problem is in this assertion: ​https://git.haiku-os.org/haiku/tree/src/system/kernel/locks/lock.cpp#n929

This assertion was added about two years ago in hrev53340.

The regression is suspected in hrev55671.

I'm attaching the syslog for the assertion message and the call stack as a picture.
