Subject: Re: kern/103256: [em] em0: watchdog timeout -- resetting (6.1-STABLE)
Date: Sat, 30 Sep 2006 20:38:27 -0400
Hello,
I can confirm this problem on an SMP amd64 machine (Core 2 Duo,
Supermicro PDSMI+ motherboard) with built-in Intel 82573V and 82573E
PCI-Express gigabit NICs and an Intel 82545GM PCI-X gigabit card.
Both 6.1 and 6.2-BETA1 exhibit the same behavior: starting a download
(e.g., portsnap fetch) is enough to trigger the timeout and a loss of
connectivity on the PCI-E NICs, but not the PCI-X one.
The 82545GM card works fine without debug.mpsafenet=0, but the 82573s
will only work with debug.mpsafenet=0. I have several of these servers
which are not in production, so I can test whatever patches may be
necessary.
Output of pciconf -lv and dmesg follow.
