Hi,
I'm experiencing this bug too. I'm using 2.6.26-2-686 on my linux router
which runs
on D945GCLF2 with Intel Atom 330.
The problem continues randomly 5-6 times a day. It causes delays in
network traffic up to 6s.
Is there any possibility that the fix will be available in stable linux
kernel?
dmesg log follows:
