Description Thomas Zehetbauer 2004-09-27 19:34:54 EDT
Starting cups with HP 6300C scanner connected on USB causes the kernel
error message "usb 2-3: control timeout on ep0in" to be printed 5
times with about 5 seconds delay each.

Sep 28 01:36:24 hostmaster cups: cupsd shutdown succeeded
Sep 28 01:36:24 hostmaster kernel: hal[24383]: segfault at
0000000000000000 rip 0000000000400ec7 rsp 0000007fbfffd400 error 4
Sep 28 01:36:29 hostmaster kernel: usb 2-3: control timeout on ep0in
Sep 28 01:36:44 hostmaster last message repeated 3 times
Sep 28 01:36:45 hostmaster cups: cupsd startup succeeded
Comment 1 Thomas Zehetbauer 2004-09-27 19:45:54 EDT
I forgot to mention the relevant package versions: cups-1.1.21-2,
kernel-, hal-0.2.98.cvs20040923-1
Comment 2 Warren Togami 2004-09-28 03:41:31 EDT
Comment #1 indicates that you are not using a Fedora kernel.
Comment 3 Thomas Zehetbauer 2004-09-28 19:18:04 EDT
Warren: According to Alan Cox there is no general rule to discard bug
reports from users of non Fedora supplied kernels. Additionlly this
bug can be reproduced with kernel-2.6.8-1.541.x86_64

Tim: Alan thinks this is a bug in hal, as it is triggered by cups I
initially attributed it to cups
Comment 4 David Zeuthen 2004-09-29 03:15:25 EDT
I would be surprised if this was a bug in hal as we doesn't do
anything for scanners. Does stopping the hal daemon, 'service
haldaemon stop', stop this continual logging?

Please try 'service haldaemon stop', and run 'hald --verbose=yes
--daemon=no' and attach the output to this bug report. IF this
succeeds please also attach the output of 'lshal'.

Comment 5 Thomas Zehetbauer 2004-09-29 06:04:20 EDT
I have just traced this down to be a kernel problem, the error message
occurs whenever reading /proc/bus/usb/devices, cups' canon driver does
this on startup, hald every few seconds, I have filed a kernel bug:
Comment 6 David Zeuthen 2004-09-29 10:03:05 EDT
Thomas, thanks for figuring this out. In fact, I plan to change hal to
not read the /proc/bus/usb/devices file since all that information is
also in sysfs as of 2.6.6.
