Hi David and Misc@,
I already use the rev1.199 source code which back out the 1.197 source
code. But I'm going to give it a try on a non-production machine with
identical h/w.
Thanks,

hi,
can you please try this diff and see if it solves your panics?
Hi David and Misc@,
I already use the rev1.199 source code which back out the 1.197
source code. But I'm going to give it a try on a non-production
machine with identical h/w.
That would be much appreciated, thank you.
Thanks,

In gmane.os.openbsd.misc, you wrote:
If there's any diffs for the driver?
this backs out the commit which will have caused the problems
you saw and should restore it to working behaviour.
please can you give us details about what the machine was doing
when it crashed please? just booted, or running for a while?
if you can test, does it still happen if the network cable is
disconnected?
The machine was rebooting, after intiatiating /etc/hostname.em* scripts,
which contains,
/etc/hostname.em0 -- onboard NIC
up
/etc/hostname.em1 -- PCI card NIC
up
media 100baseTX mediaopt full-duplex
/etc/hostname.em2 -- onboard NIC
mtu 1600
up
and it hangs. Happens even when I disconnected the cables. I had to
disabled it from bios then it stop complaining.
Hope this helps,
Best Regards,
Insan

The 82573E is fairly uncommon, I don't think there are too many people who can test this. I've been trying to find systems it fails on (because I have a few routers with em(4) in them and I need to check they'll be ok before I upgrade them - always wise, but doubly so around the time of a hackathon especially when it has specifically involved work on this driver) and haven't yet seen a problem.
