Hi,
We do experience some trouble with em.
1. em0: watchdog timeout resetting
Network hangs, server becomes unreachable, and after a few minutes,
console doesn't respond anymore.
We tried to type something at the console prompt and we got some
"chinese" characters :)
We had to reboot badly. twice. Then we switched to an xl network card.
The problem occurred under load (heavy for our use) : nightly nfs backup
that wasn't completed, samba home directory for 300 users, squid
just 5 minutes after users began to work at the office. Really bad.
2. We are using a 6.1 release.
We were using an old 5.2.1 before that. And we already had some network
hang followed by server hang
that's why we upgraded to 6.1. really bad idea. The problem occurs once
a week now.
3. em cards are experiencing the problem. We bought a brand new one, and
it stills occurs.
So we are now using the integrated xl card. It works fine, but at 100Mbps.
4. It is an SMP machine. We are using the default kernel.
5. machine not hyperthreading capable
6.ioapic0 <Version 1.1> irqs 0-23 on motherboard
7. no code patch, default configuration, default kernel
8. 4BSD scheduler
I can't do a lot of test with this server, as it is a production one.
Hope this will help you to fix.
See below, vmwtat, dmesg and pciconf
Regards
Stephane
