Hi Alan,

using 2.4.20-BK tree gives me:

flushing ide devices: hda hdd

at reboot time in an endless loop drawing over the screen. No reboot will be 
made, I have to do that either by sysrq-b or reset button.

Using:

[*]   PCI IDE chipset support
[*]     Generic PCI bus-master DMA support
[*]       Use PCI DMA by default when available
<*>     Intel PIIXn chipsets support
[*]   IGNORE word93 Validation BITS

root@codeman:[/] # hdparm -i /dev/hda

BTW: The attached patch is needed to build the 2.4.20-BK tree successfully
     because "local_irq_*" is missing and ld complains about undefined
     reference at linking time.

Any hints to fix that flushing ide bla foobar thing?

TIA!

ciao, Marc
