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.
