[BUG] pdc20267 and dma timeouts

[Ed Tomlinson]

Hi,

I am running 2.4.4 with the lvm -0.91 beta7 patches applied on a debian
sid base.   When I checked my box this morning the follow greeted me on 
the serial console.  The reiserfs errors are caused by the DMA timeout.
Note this is a ultra100 controller not supporting raid.

with another lost interrupt entry added every couple of seconds.  Looks like
the reset is not working...  Here is a lspci -vv of the device
