Hi,
my server paniced with the string
"panic: vm_fault: fault on nofault entry, addr: dadb1000".
I've attached the backtrace. The backtrace looks similar to the backtrace in
kern/115374.
Is this a known problem? Is there a patch available?
I can provide the kernel config and dmesg output, if needed. And, if necessary,
I can enter additional commands to the debuger, but I'm not able to
reproduce
the panic.
bye,
Hilko
