Re: panic: vm_fault_copy_wired
Hi,
This problem came back after an unclean, forced reset of a crashed VM.
This time I managed to log startup messages via serial console.
After this problem occurred, it would persist between resets. I had to
boot d-i, drop to a shell, run fsck.ufs -y on the root partition (this
just marked it clean; no modifications were needed), and after that it
would boot normally again.
I have no swaps configured in /etc/fstab. I've set VERBOSE=yes in
/etc/default/rcS for next time...
