sky2 0000:02:00.0: error interrupt status=0x8

[Nathan Grennan <linux-netdev@cygnusx-1.org>]

    I am using the sky2 driver in kernel-2.6.23.15-137.fc8.x86_64 with 
my Marvell 88E8056 to do iSCSI. I have many errors in dmesg like the 
ones below. If I count just the lines that match the first one, there 
are over 1500. If I include the suppressed lines it is over 100k. At 
first I got three of these doing something and then didn't see it for a 
while. I suspect the 100k came from a download of an 8gb file from the 
internet that was being written to the remote machine via iSCSI. The 
download took about an hour and fifteen minutes. I would ignore just 
three of these, but 100k of them suggests a real problem to me.

sky2 0000:02:00.0: error interrupt status=0x8
printk: 77 messages suppressed.


 I am using a MTU of 9000. Between the two computers is a D-Link 
*DGS-2208 *switch that supports jumbo frames. The remote card uses the 
forcedeth driver.

 This from the kernel package changelog seems like it might apply.
