FreeBSD unstable on Dell 1750 using SMP?

[Rutger Bevaart]

Strange indeed.

On a 1750 with bge's:
475 mbufs in use
501/25600 mbuf clusters in use (current/max)
0/3/6656 sfbufs in use (current/peak/max)
1120 KBytes allocated to network
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
100 calls to protocol drain routines

On a 2850 (hardware identical to an 1850):
$ netstat -m
4294966848 mbufs in use
565/25600 mbuf clusters in use (current/max)
0/67/6656 sfbufs in use (current/peak/max)
1018 KBytes allocated to network
0 requests for sfbufs denied
0 requests for sfbufs delayed
16449 requests for I/O initiated by sendfile
589 calls to protocol drain routines

Both experience the "auto reboot" feature. The mbufs on the 2850 look  
like a counter (signed/unsigned) bug, maybe even just in the  
printing. Other than that I'm having a hard time interpreting these  
results.
