Hello,
I'm having a panic with the latest kernel build of my -Stable file server
(sources cvsupped around yesterday evening, CEST). The panic happens soon
after entering multi-user :
panic: vm_phys_paddr_to_vm_page: paddr 0xf0000 is not in any segment
KDB: enter: panic
[thread pid 1005 tid 100154 ]

The previous kernel is older (around 22 august) and works as expected.
Some idents for the panic kernel are : (ie after SVN rev 196838)
