Subject: ide.c and compactFlash

Hi all.

I got problems with the IDE code which causes the kernel to freez after 
printing out:

hda: status timeout: status=0xd0 { Busy }

kernel used: 2.4.18 crosscompiled with Montavista tools (ppc_82xx-gcc 
(GCC) 3.2.1 20020930 (MontaVista))

The ide interface chip is a PD6729 configured to ATA mode.

CompactFlash cards: winsys 1GB industrial grade and simpleTech 1GB 
industrial grade.

I beleive this is a timing issue and have tried to increase a udelay () 
to 2 microseconds (instead of 1 microsecond) in the ide_wait_stat() 
function - it took longer time to freez, but it still freezes...

Any clues?

Regards
Espen M. Rutger
