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..)
