Description Pekka Savola 2006-11-22 08:51:24 UTC

Description of problem:
After I resume from suspend on my FC6 laptop which I just updated from FC5
(latest kernel, 2.6.18-1.2239.fc5) to FC6 (latest kernel, 2.6.18-1.2849.fc6)
using yum, the syslog is filled with the following:

Nov 22 08:47:37 dhcp-142 kernel: ohci1394: fw-host0: isochronous cycle too long
Nov 22 08:47:42 dhcp-142 kernel: printk: 6642 messages suppressed.

However, the system appears to be working OK nonetheless.  I haven't tried using
USB yet, though.

Version-Release number of selected component (if applicable):
Linux dhcp-142.csc.fi 2.6.18-1.2849.fc6 #1 SMP Fri Nov 10 12:45:28 EST 2006 i686
i686 i386 GNU/Linux

Note that this system is single-processor Mobile P3/1200.

How reproducible:
Resume from suspend.

In /etc/acpi/actions/sleep.sh I have:

...
# remove USB 1.1 driver; assumes /etc/modules.conf has an alias for this
modprobe -r usb-controller

 ...
 and at the end:

# reload USB 1.1 driver
modprobe usb-controller

(This is based on instructions on how to get suspend working OK as FC doesn't
include default ACPI actions..)

Comment 1 Jon Stanley 2008-01-08 01:48:46 UTC

(This is a mass-update to all current FC6 kernel bugs in NEW state)

Hello,

I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.

http://fedoraproject.org/wiki/KernelBugTriage

I am CC'ing myself to this bug, however this version of Fedora is no longer
maintained.

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!

Comment 2 Pekka Savola 2008-01-21 07:05:14 UTC

This no longer happens on FC8 kernels, so I'm closing this bug.
