Subject: Upgradeing 2.6.21.7->2.6.22.9 kill my network (sky2): sky2 eth0: rx
 error, status 0x402300 length 60

Hello,

After upgrading my kernel from 2.6.21.7 to 2.6.22.9 my 88E8053 no longer 
works:

sky2 0000:02:00.0: v1.14 addr 0xcfffc000 irq 17 Yukon-EC (0xb6) rev 1

I also compared lspci output from both 2.6.21/2.6.22 and it is the same:

It is quite strange as on the other similar system (only rev 1/2 
difference), sky2 driver from this 2.6.22 kernel solved my problem 
(network hangs):

sky2 0000:03:00.0: v1.14 addr 0xf1000000 irq 16 Yukon-EC (0xb6) rev 2
sky2 eth0: addr 00:16:e6:5f:64:24
sky2 eth0: enabling interface
sky2 eth0: ram buffer 48K
sky2 eth0: Link is up at 1000 Mbps, full duplex, flow control both

Best regards,
