First please excuse for my bad english.
Recently I checked out out the 2.1.131 kernel.
When I do a cat /proc/bus/pci/00/0f.0, which is imho the port of my
Dawi 2975 U (NCR 53c875 (rev 4).) controller, then following occurs:

Sometimes the kernel died with the following message. (Not logged,
typed manually) After this the kernel react only to sysqr messages.
After a reboot the filesystem is partially destroyed.

The same thing occurs when I switch on dma with hdparm for the ide hdd.
hdparm -d1 /dev/hda.
When I copy a few files then the kernel died like before.
The dma mode works fine with win95, the other stuff fine with kernel 2.0.35.
Some infos (from 2.0.35)
