IDE problem in 2.4.21-pre1 --> pre5

IDE problem in 2.4.21-pre1 --> pre5

[Brad Campbell]

G'day all,

Just upgraded a system I am developing from 2.4.20 to 2.4.21-preX and 
noticed this 20 second hang with ide on bootup.

I am loading a system from a CF card using 2.4.19 as a bootstrap using 
two kernel monte to load the new kernel off the filesystem.

With 2.4.20 this was smooth and quick, with the new ide in 2.4.21-pre
it hangs for about 20 seconds while detecting the flash disk. It 
proceeds fine from here after resetting the interface, but it never used 
to do this. I have tried most combinations of config settings, and 
cmdline settings like ide=nodma hda=autotune hda=flash and whaterver 
else I could find in ide.c that looked like a likley suspect. Also tried 
with use Multimode by default and DMA by default.

Hardware is VIA EPIA800 Mini-ITX board with a homebrew ide-CF adapter.
This has not been an issue previously.

Kernels 2.4.21-pre1 --> pre5 all behave the same.

dmesg snip and .config | grep ^[C] follow.

Problem still exists in -pre6 (released about an hour before my previous 
E-mail)
I also tried ide0=reset to reset the ide bus in case the 2.4.19 kernel 
had left it in some strange state.
Tried with the VIA driver compiled in also.. No joy..

Included hdparm -i /dev/hda ; hdparm -I /dev/hda and /proc/pci below.
