| |
I've got a Nehalem testbox that developed a new e1000e problem in this merge window: after a few minutes of uptime the network interface goes dead - no rx and no tx. If i ifdown/ifup the interface it comes back. If i wait too long then even ifdown/ifup does not help anymore - only a reboot.
Other e1000e using testboxes i have are working just fine - so the problem is specific to this hw.
Is this a known problem?
I have this hw:
01:00.0 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) 01:00.1 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02)
If this is a new problem, what kind of other info do you need from me to debug and fix this?
I started seeing this very early in the merge window, so candidates would be one of these early commits:

If you suspect a specific list of commits i can test their revert. (But the box is a slow booter and the problem can take up to 15 minutes to trigger so i'd rather not spend half a day bisecting it, if it can be avoided.)
Thanks,
Ingo
