           Summary: uhci_hcd: host controller process error
    Kernel Version: 2.6.19.1
            Status: NEW
          Severity: normal
             Owner: greg at kroah.com

Most recent kernel where this bug did *NOT* occur:
Distribution: Debian Etch
Hardware Environment: Intel Pentium M processor 1.60GHz  (HP Notebook nc6120)
Software Environment: 
Problem Description:
I'm getting errors like this:

uhci_hcd 0000:00:1d.1: host controller process error, something bad happened!
uhci_hcd 0000:00:1d.1: host controller halted, very bad!

Sometimes already while booting up, sometimes after some minutes... I was not
able to find out what causes this.
As I read in an similar bugreport (bug 6809) I recompiled the kernel with 
CONFIG_USB_DEBUG turned on and loaded the uhci-hcd module with debug=2
I will attach files with dmesg and syslog output(at the moment I don't see how).

To see if it is only a 2.6.19 problem I compiled also the latest 2.6.17 and 2.6.18.
Same problem on 2.6.17.14 and 2.6.18.6(happens not so frequently). 
Is this maybe a hardware issue or should I try also 2.6.16.35?

After getting this error messages (Controller halted) I'm not able to switch the
WLAN(ipw2200) on (kill switch). 

Steps to reproduce:
Unable to see conditions with causes halting of controller.
