Re: [Linux-usb-users] Problem, irq 23: nobody cared (try booting with the "irqpoll" option)

[Dylan Taft]

Thanks for the reply.
This started happening in 2.6.21 suddenly, which is why I tried
upgrading to 2.6.22.  It seemed to have started happening when my
bluetooth light mysteriously went on one day.  I went into bios and
disabled some IO devices earlier today; "Wireless USB", my firewire
port, and the bluetooth adapter.  The bluetooth light went off, and
this has not happened since.  I think it's safe to say it's not going
to happen again, since I was getting the IRQ messages every few
minutes and it's not happening at all now.  I don't have any hardware
to test of those IO ports were working or not anyway...

Some of the hardware in this laptop behaves strangely, like using the
madwifi drivers with the Atheros wireless will throw the device into a
state where it will not be recognized by ndiswrapper or anything until
I power down and pull the battery or boot Vista and then boot linux.
That's a known issue with the madwifi drivers and my chipset, I'm
wondering if something similar happened with the bluetooth
chipset/drivers.

If anyone needs more info or wants me to try to reproduce the problem
let me know, but it's working for the moment again.   It looks like
others have had the same issue.

[Linux-usb-users] Problem, irq 23: nobody cared (try booting with the "irqpoll" option)

[Dylan Taft]

Hi all.  I'm using a vanilla linux-2.6.22 kernel.  I just noticed I
get these messages while my laptop is sitting around doing nothing, 2
of my USB ports get disabled.   I'm not sure what's causing them, to
reproduce I just let the laptop sit idle for maybe 5 minutes. rmmod
uhci_hcd and modprobeing it brings it back for a few more minutes but
the message pops back up.  I'm using a Lenovo T61.  Does anyone have
any possible suggestions or kernel patches I can try?  Thanks!
