Reproducible panic while playing with modules

[Hasso Tepper <hasso@xxxxxxxxx>]

As chlamydia is still down, I'll post it here.

USB serial converter (tried umct(4) and uplcom(4)) connected and working.
Unload both modules (hw specific and ucom(4) as well) and load hw specific
module again -> panic.

panic: vm_fault: unrecoverable fault at 0xdeadc000 in entry 0xc06d12a0

Any ideas?

Creating core isn't successful and I haven't played much to see if there
is easier sequence to repeat it - it takes too much time to reboot after
panic.
