[kernel] PANIC: _mutext_lock (): double lock of 0x8019b348 by thread 697157

[diver]

This is hrev42467 , gcc2hybrid.

I was trying to reproduce #6673 by running many instances of:

for i in `seq 1 10000`; do mimeset -apps -f /system/apps/*; done

While executing it Haiku was almost unusable, so I left it in this state for some time. Several minutes layer kernel crashed with this panic message.

Apparently a NULL-pointer is dereferenced in vm_cache_acquire_locked_page_cache(). I don't see how that can happen, though.

Still reproducible?
