Hi all,
we've recently got some Asus P5E Deluxe based boards with Yukon NICs on it:
03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E
Gigabit Ethernet Controller (rev 12)
Subsystem: ASUSTeK Computer Inc. Device 81f8
Flags: bus master, fast devsel, latency 0, IRQ 762
Memory at fcffc000 (64-bit, non-prefetchable) [size=16K]
I/O ports at e800 [size=256]
Expansion ROM at fcfc0000 [disabled] [size=128K]
Capabilities: [48] Power Management version 3
Capabilities: [50] Vital Product Data <?>
Capabilities: [5c] Message Signalled Interrupts: Mask- 64bit+
Queue=0/0 Enable+
Capabilities: [e0] Express Legacy Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting <?>
Kernel driver in use: sky2
Kernel modules: sky2
Kernel is 2.6.27.21 (vanilla) with sky2 version 1.22, but we have seen
similar issues with 2.6.26 and 2.6.28 kernels (Debian based or vanilla).
We do see this error quite often, especially during installation and
afterwards if doing "innocent" stuff like browsing through dmesg or
doing 'lshw|most':

After this it takes a couple of minutes until the NIC reports back to
ping requests.
Anyone an idea what this is about?
TIA
