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.
Yes, that's correct. But then 6.6.6 is faster, so it may be that we have a
timing problem in any driver when they share interrupt with a Gigant locked
driver. Isn't there a new non-Gigant USB driver that is waiting for
testers? I have two workstations with em that needs usb that I could test
the combination on.
