PROBLEM: sky2 hangs

PROBLEM: sky2 hangs

[Peter Trifonov]

Hello,

I have got a PC based on Gigabyte GA-965P-S3 motherboard with an integrated
Marvell Yukon 88E8056 PCI-E gigabit ethernet controller. 

I am using OpenSuSe Linux 10.2 x64/SMP  with 2.6.18.2-34-default kernel.

Everything works fine when the network load is low. However, if a big file
transfer is initiated,
the network stops working completely,  and the following message is logged:

Apr  2 20:44:07 bullet-lin kernel: sky2 0000:04:00.0: pci hw error (0x2010)

In some cases the system freezes in a short time after this. 

ifconfig up/down and reloading the sky2 kernel module does not help.
ifconfig says also "unknown device 4364 rev. 13"

The driver provided by Marvell fails to compile. 

Everything works perfectly under WinXP x64.


Please let me know if there is a way to make this NIC to work under Linux.

Many thanks in advance. 

With best regards,
P. Trifonov

There have been several updates since 2.6.18. Please try and reproduce with
2.6.20 or later kernel. Or contact the vendor to update their kernel.

Thanks a lot!

After installing 2.6.20 kernel the NIC works perfectly!

Dear Stephen,

Unfortunately the problems with sky2 started again.

I bet you have 88e8056 chip.  There is some problem with the bus interface
and the sky2 driver (and the vendor sk98lin driver), that causes all sorts
of out of order device access problems.  Still investigating....

For 2.6.21, I ended up blacklisting this version of the chip until the problem
is resolved.

Windows driver works perfectly with it...

I can give you SSH access to that box if this can help you.

Thanks but I have a system with same problem.

I mean WinXP x64. I have not tried 32-bit 
Windows and Linux with this NIC.
