Once booted a new kernel, linux can't mount hdc and reports interrupt lost.

Oct 10 03:34:11 read-only kernel: hdc: lost interrupt
Oct 10 03:34:11 read-only kernel: hdc: lost interrupt
(still tries to mount ....)
And this somehow mishandles the IRQ detections for hdc.
When I enabled USB IRQ assigning in BIOS. Everything worked :)
Now I've got these messages :)

as for 2.3.18ac, 2.3.19 that's fine.
