I would like to request that some useful work on networking be MFCed from

The thing that's worried me, following only [EMAIL PROTECTED] traffic,
were the reports about the new em driver (6.6.6?) causing hangs and other
problems with people who have been updating RELENG_6 - have those who had
those problems seen their issues resolved? I've got remote boxes using
em that I can't risk making inaccessible and can't test locally.
All my problems with watchdog timeouts and em 6.6.6 occurred when em shared
interrupt with USB but I don't know if it's MB, em or usb that's the problem.
Removing USB from the kernel or switching to polling and the driver works
just fine.
The fact that one of my test machines didn't have any problems was because it
had no USB in it's kernel. I had removed USB as I had problems with watchdog
timeouts with the bge driver when I first upgraded to the D915GAV MB ages
ago. The bge also shared interrupt with USB.
Thanks. /var/run/dmesg.boot says my em0 and em1 don't share an IRQ with
USB or anyone else, so sounds like I'm in the clear, yay. But it still
seems like something the vendor (Intel?) should be looking into before a
another release on RELENG_6 is cut - even if USB is the culprit, it
sounded like the problems started for em users when the driver was updated
from 6.2.9 to 6.6.6.
