>Description:
shared /cdrom in /etc/exports:
/cdrom -ro -mapall=nobody
ran:
#nfsd -u -t -n 4
#mountd -r
#/usr/sbin/rpcbind
#/usr/sbin/rpc.statd
#/usr/sbin/rpc.lockd
now from another box, when I try to nfs mount:
#mount -t nfs myhost:/cdrom /some_dir
my system hangs for 5-10 secs then reboots.
Here's the kernel dump:

My pc is a HP D530 supposedly with hypertheading, so I built a SMP kernel, but it looks like hyperthreading is deactivated or not functionning on my system. It's running an old BIOS version, locked BIOS too(company policy..).
I also have acpi disabled (in /boot/, it caused me some problems with my bge on board network interface (keeps resetting)
