copying from DVD drive causes crash: vm_fault: pager readerror, pid 13421 (cp) on FreeBSD 5.3-STABLE

[Christoph Steigmeier]

Hello

I observe a similiar behaviour here on an ASUS Laptop with a
MATSHITAUJ-831D/1.00 DVD-RW Drive. Altough only with DVD's, but not with 
CD's. Installed is FreeBSD 5.3-RELEASE-p2. The only difference to the 
GENERIC kernel is that I added the device atapicam to the kernel. The 
failure occures with both way accessing the drive (acd0 and cd0).

If you need more output, pls. tell me.

Chris
