Subject: [BUG] skge 0000:02:05: read data parity error

Hi All!

It is fully reproductable under 2.6.22.15, 2.6.23.13 (all tainted and
not tainted [4 different kernel] ) and 2 different PC:

[BUG] skge 0000:02:05: read data parity error
[BUG] skge 0000:02:05: read data parity error

steps:
1. login as root
2. start mc
3. cd /sys/bus/pci/drivers/skge/0000:02:05.0
4. press F3 (mcview) on resource0
5. the system hang up, without panic or bug ... only this message
printed 2x: [BUG] skge 0000:02:05: read data parity error

when I used cat for show what is in file , then bocome this message:
 cat: resource0: Input/output error
but the permissions is:
 -rw------- 1 root root 16384 2008-01-14 20:36 resource0

when I used mcview for show whats in file, then the system hang up,
and not reagiert neither for SysRQ-s, only for hard reset.
