Hi all,
In 9 from 10 boots I get the panic below. If I remove everything
from /tmp/vi.recover the box is bootable again. It looks like vi.recover
triggers a bug in the vm_system.
Anybody has some idea ?
A kernel from June works fine. RELENG_6 works fine.
A fresh kernel from today shows:
Unread portion of the kernel message buffer:
