Subject: Sky2 Driver Issue

Hi,

A couple of kernels ago, I ran into an issue with the sky2 driver.
Basically, I began getting repeated errors on my console of the
following:

Oct 21 16:33:39 holly kernel: sky2 0000:04:00.0: error interrupt
status=0x80000000
Oct 21 16:33:39 holly kernel: sky2 0000:04:00.0: error interrupt
status=0xc0000000

Which eventually led to:
Oct 21 16:33:49 holly kernel: printk: 92 messages suppressed.

Here is a section of the log that may be useful:
Oct 21 16:33:37 holly kernel: sky2 eth1: enabling interface
Oct 21 16:33:38 holly dhclient: DHCPDISCOVER on eth1 to
255.255.255.255 port 67 interval 8
Oct 21 16:33:39 holly kernel: sky2 0000:04:00.0: error interrupt
status=0x80000010
Oct 21 16:33:39 holly kernel: sky2 eth1: Link is up at 1000 Mbps, full
duplex, flow control both
Oct 21 16:33:39 holly kernel: sky2 0000:04:00.0: error interrupt
status=0x80000000
Oct 21 16:33:39 holly kernel: sky2 0000:04:00.0: error interrupt
status=0xc0000000
Oct 21 16:33:40 holly kernel: sky2 0000:04:00.0: error interrupt
status=0x80000000
Oct 21 16:33:40 holly kernel: sky2 0000:04:00.0: error interrupt
status=0xc0000000
Oct 21 16:33:41 holly kernel: sky2 0000:04:00.0: error interrupt
status=0x80000000
Oct 21 16:33:41 holly kernel: sky2 0000:04:00.0: error interrupt
status=0xc0000000
Oct 21 16:33:42 holly kernel: sky2 0000:04:00.0: error interrupt
status=0x80000000

These messages are appearing on all the VTs, and because they keep
popping up, I can't reasonably use the consoles to test if the network
driver is working.

The kernel I've got going at the moment is 2.6.23-rc9 with git
revision g804b3f9a, and it's fine. The error surfaced _sometime_
after this. Attached is my .config.

I'll try rebooting and pinging the machine to see if the network
driver is working, and this is just (unnecessary?) spew from the
kernel.

Your system is not supporting MMCONFIG access to allow driver to turn off
PCI express error value. It looks like the hw error irq mask doesn't work
as expected either.

What is your kernel config?

I bisected the kernel, with the following results:

Whoops. And of course, the first bad revision is:
