Hi,
I've noticed with the kernel's (two different machines) 2.6.28 and
2.6.29-rc2, that the NIC's were hanging.
In the kernel output i have:
---
sky2 eth0: receiver hang detected
sky2 eth0: disabling interface
sky2 eth0: enabling interface
sky2 eth0: Link is up at 1000 Mbps, full duplex, flow control rx
---
the NIC is:
---
03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E
Gigabit Ethernet Controller (rev 15)
---
i've searched the web a bit and i saw some info that this seems to have
been fixed in arround 2.6.23 +/-, but still happening.

Marvell ram fifo has hardware problem where if it gets full it hangs.
The driver snoops to look for this, and the should recover. Unfortunately,
the recovery may take long enough to disturb connections.

I see Stephen,
Well, no problem then since the driver don't crash.
with 2.6.27 it used to crash.
I'll stay tunned to see it with 2.6.28+ the crash will happen, and if yes,
how do i get the dump?
That info doesn't get logged in the logs don't know why (maybe some
dumbness from me)
