next in thread | raw e-mail | index | archive | help
Dual opteron Tyan s2882 with onboard intel (fxp) and broadcom (bge).
System essentially freezes during network traffic through fxp. Not only
that, but any process that was started that used fxp (cvsup, for
example) will lock. Rebooting will result in an unclean unmount as it
"gives up on 64 buffers".
Anyway the exact error message is:
kernel: fxp0: can't map mbuf (error 12)

Using the broadcom gigE connector resolves the issue ...
