irq XX: nobody cared! and uhci_hcd

From: Rene Rebe
Date: Fri Jul 01 2005 - 10:19:11 EST

Hi all,

I have a tiny Sumicom box with Intel (ICH5/ICH5R) w/ Celeron CPU in front of me, that expose quite some bugs in recent Linux kernels. I tested with 2.6.8 (Debian) 2.6.11 and 2.6.12. .12 output attached below.

First if of all I have to use acpi=noirq or pci=noacpi to get the e100 interrupt routed at all. Otherwise no network packet will go on the wire or is received.

But even with this workaround USB 1.x devices are not functional due to the IRQ for those devices is disabled because nobody cared:

uhci_hcd 0000:00:1d.0: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #1
uhci_hcd 0000:00:1d.0: new USB bus registered, assigned bus number 1

uhci_hcd 0000:00:1d.0: irq 10, io base 0x0000e000

Of course USB 1.x transfers stall due to no IRQ gets received anymore.
