crashes on newly updated freebsd 6.1 box..

[Jason]

I was running 6.0 stable on my dual Pentium III/733Mhz box and was running fine and dandy..
I did makeworld to upgrade to 6.1 and its been crashing weekly if not less.. the only thing I get on the 
console is 
Sleeping thread (tid 100075, pid 4401) owns a non-sleepable lock
panic: sleeping thread
cpuid = 0
KDB: enter: panic

I couldnt break in on the console and had to hard reboot the box. I was thinking this is 
kern/99094 but im not sure. I dont have any linux fs references in my /etc/fstab..
