Subject: [2.6.9] unhandled OHCI IRQs...
Date: Sun, 24 Oct 2004 22:20:13 +0200 (MEST) [thread overview]
Message-ID: <16118.1098649213@www5.gmx.net> (raw)
When plugging in an Epson C62 USB 1.1 printer to my nForce 2 OHCI + EHCI USB
controllers, the IRQ doesn't seem to get handled [1]. Tried both with
acpi=noirq and without, printer support and full USB support enabled. Kernel
is 2.6.9.
Any ideas?
