Oops... I simply sent file over scp and didn't checked that KMail
extracted it (photographer is my co-worker, he sent photo attached in
private email) to /tmp with mode 0400... Sorry to all tried and
failed. :( Fixed now. And no, it was not short enough, until
skipping "linking mismatch" messages. But here it is without them:
kernel: page fault trap, code=0
Stopped at pf_icmp_mapping+0x38: movzwl 0x4(%rax),%eax

As far as I remember, USB keyboards are useless in ddb(4) - am I wrong?
Of course, I tried different PS/2 keyboards, that worked fine on another
machines - just fail. There were other issues with keyboard
(controller), even during install, but I was too busy to worry about it.
Yes, I know that serial console should be very useful, but current
situation in my company do not give me opportunity to order one for
minimum next two months. :(
"pf: state key linking mismatch" message is very easy reproducible for
me, though: not directly ("touch that and it will happen"), but often
enough ("it'll eventually happen in a minute, just open and close some
connections").
