Bug#609994: sky2: hw csum failure
Hi,
[reference: http://bugs.debian.org/609994]
I have a Marvell ethernet controller which presents some failures when
'rx checksumming' is enabled,
here is the model:
$ lspci -vvs 03:00.0
03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E
Gigabit Ethernet Controller (rev 15)
Subsystem: Micro-Star International Co., Ltd. Marvell 88E8053
Gigabit Ethernet Controller (MSI)
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B- DisINTx+
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 32 bytes
Interrupt: pin A routed to IRQ 44
Region 0: Memory at fdbfc000 (64-bit, non-prefetchable) [size=16K]
Region 2: I/O ports at 7c00 [size=256]
[virtual] Expansion ROM at fda00000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: sky2
At first I thought it was due to the MTU size, so I tested different
values but unfortunately without positive effect.
Overall this issue appears randomly when the incoming traffic is high. I
tested 2.6.32, 3.1.1, and 3.2-rc3, sadly
all are affected. Finally, the only way to avoid those failures is to
disabled 'rx checksumming' (ethtool -K ethX rx off).
Here is the stack trace:
