I have been having problems enabling my EIDE controller's support for DMA.
The controller works fine when setting the flags to 0x80ff, but it barfs whenever
trying to set the flags to 0xa0ff.
dmesg says the controller is busmaster capable, yet it hangs when trying to mount
the filesystem. Here is an output of dmesg, together with the error messages:

changing root device to wd0s2a
--> (now the system hangs, with the hard drive LED on, timing out for 5-10 seconds,
and then the output:)
wd0: interrupt timeout:

wd0: wdtimeout() DMA status 0
--> ( now another short timeout... )
wd0: interrupt timeout:
wd0: status 50<rdy, seekdone> error 1<no_dam>
Now the system hangs completely and stops responding.
It works fine when I set the wdc0 flags to 0x80ff, however, I was hoping
to find out what is wrong with it.
The motherboard Chipset is a TXPro one, are there any known problems/faults with
this kind of chipset?
Thanks, Gilad.
