Subject: Loading e100 and uhcd-hcd at (almost) same time disables IRQ with 2.6.16-rc4
Date: Wed, 22 Feb 2006 11:43:42 +0100 [thread overview]
Message-ID: <43FC405E.7010705@packetalarm.com> (raw)
This is with a supermicro P3TSSE mainboard, with an Intel 815E chipset, where
the two integrated network adapters (Intel82559 10/100 Ethernet) and one of the
two usb host adapters share the same IRQ (irq 11).
When udev synthesizes hotplug events during boot and there is interrupt activity
(e.g. by flood pinging one interface) I get an "irq 11: nobody cared" message
followed by a traceback and "Disabling IRQ #11". After that unsurprisingly both
network adapters are dead which is unfortunate as this usually is a headless
server machine.
I reproduced the problem on another identical hardware, so faulty hardware is
(almost) ruled out. The bug is already present in 2.6.14, I did not try to trace
it farther back.
dmesg from normal and failed boots and further info can be found on
