OK, I have done some more testing....

How to avoid getting HTML messages from Outlook?

I get these three printouts when inserting a compact flash disk
(SuSE Linux 2.4.21-144-smp) - is the stack intentionally this fit?
or is it an unexpected code path?

I have had other interrupt related problems, it usually locks up :-(
This time I run with "nosmp noapic"

The ide-cs is now forced to use irq 3 (When running noapic others
seems busy... with apic and using irq 6 or 10 computer has
locked up...)

I will try irq 3 without one of the options to see if the computer still
survives...

- new data -

Easier said than done - they require each other!
But I noticed that reducing 'stackwarn' and 'stackdefer'
to under the level warned about helps (might be luck)

Summary:
  Some routines allocate to much stack: validate_cis?
	several subtypes in the union cisparse_t are quite
	big (>250 bytes)
  This eats stack (to much?) or only close enough to
  trigger 'stackdefer' which might stress the drivers SMPness?
