HI guys
this is my first post so bare with my lousy English..
i'm using ARCH linux on ASUS-PT6 delux I-7 CPU system.
every now and then, i get a crash in my network stack:

Same here. Old SiS chipset, 1 CPU. Started with 2.6.32 kernel.

I'm having the exact same problem. Didn't occur on a Debian Testing box also running 2.6.32 (if that helps).

Singul · 2010-03-24 22:59:25

Forgot to mention my Ethernet controller:

02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 20)
03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 20)

Actually it seems like I managed to solve this problem by installing the official driver from Marvell (sk18lin). It can be found on the Marvell site. Seems like the crashes do not occur anymore after replacing sky2 with that one

Singul · 2010-09-11 08:33:27

The current version of the sk98lin driver cannot be compiled with the 2.6.35 kernel, which is a pity, because it did a really good job until now.

Though, the sky2 driver in the current kernel still seems to be faulty at least for Marvell 88E8053 because the problem still persists (mainly occurs when transferring huge amounts of data, so maybe try to copy 30GiB of data beetween two systems in a network...a driver crash is almost guaranteed for me then).

Saw that other people talked about hw csum errors which caused exactly the same behaviour.

Any new info on this? It's really quite sad that the driver seems to be broken for years now :S

.:B:. · 2010-09-11 09:41:12

Has this been reported upstream in the meantime? After more than six months you'd at least expect a bug report .

If the kernel devs haven't been informed, you can't expect them a non-existent problem.

Singul · 2010-10-11 16:50:36

I have now reported it.

https://bugzilla.kernel.org/show_bug.cgi?id=20092

Singul · 2010-10-18 03:56:15

For those still having the problem, I have modified the sk98lin driver to work with kernel 2.6.35: https://bbs.archlinux.org/viewtopic.php?id=106785
