Toshiba Libretto 70CT ep0 intermittent

I used some search engines, found these rc.conf bits on a Japanese site
	saver="daemon"
	apm_enable="YES"
	pccardd_flags="-i 11"
(no I don't read Japanese) but I'd always been wary of my IRQ 5
 ep0: <3Com Etherlink III 3C589> at port 0x240-0x24f irq 5 slot 0 on pccard0
It's early to say as the fault was intermittent,
but I think the fault is now gone :-) Does it help you too ?

Maybe something else sits on irq 5 though unshown by my generic dmesg,
guessing maybe something like sound ?  Dont know.
