G'day all,
I'm still getting quite a lot of these come up in the logs when the system is under mild load. I suspect it might have something to do with running an MTU of 9000 on the main ethernet port which is directly feeding a workstation with an NFS root (and thus gets quite a high load at times)
It's not so much an issue but it does cause the workstation to stall for up to a second while it waits for data every time it occurs.
The loaded ethernet port is this one on an PCI card
0000:00:0d.0 Ethernet controller: Marvell Technology Group Ltd. Yukon Gigabit Ethernet 10/100/1000Base-T Adapter (rev 12)
This started rearing its ugly head when I moved from 2.6.5 to 2.6.9-preX and persists with BK as of about 2 days ago.
Regards, Brad
