Public bug reported:
on a hp pavilion dv904ea.
it seems that there is a irq problem. in /var/log/kern.log is a line
"spurious 8259A interrupt: irq 7". after a while of using the desktop
irq 7 is disabled (the usb2 port). i have to manually remove ehci_hcd to
get usb working again (at 1.1 speed).
the same problem is persisting in dapper and edgy as well.
** Affects: linux-source-2.6.19 (Ubuntu)
