[BUG REPORT] 2.6.21-rc7 - Yukon-EC Ultra <-> sky2 driver bug(s)

From: speedy
Date: Wed Apr 25 2007 - 21:59:41 EST

Kernel: 2.6.21-rc7
Device: Yukon-EC Ultra (0xb4) rev 2 [integrated on Gigabyte GA-965P-DQ6]
OS: Ubuntu 7.04 (Feisty Fawn)

Description:

The driver reports rx errors, drops carrier due to HW error, rmmod/modprobe combo returns carrier to sane state..
after that it works with rx errors for a while, then OOPSes the kernel in different ways each time
ie. ext3 routines, vma (traversal(?)) or this time in the workqueue. Seemingly, random memory corruption takes place.

I assume a kernel bug because of the recent git commits regarding sky2, the fact Windows XP works flawlessly and
the OOPS itself. Also, that box recently compiled the kernel, so I regard it as stable.

The bug is easily reproducible (*sigh* too easy) and occurs also with Ubuntu default kernel - 2.6.20 with
Ubuntu patches. After linux boots and crashes, the network card malfunctions even when dual-booted to Windows
(causing slowness and reboots). It takes power-off/power-on cycle to bring it back to stable state.

Thanks in advance for all help, if you need more info, .config or testing any patches, let me know.

Cheers,
speedy over&out
