Comment 6 Dave Jones 2011-12-30 23:44:11 UTC 
*** Bug 771002 has been marked as a duplicate of this bug. ***
Comment 7 Dave Jones 2011-12-30 23:46:55 UTC 
711002 is a trace from a different driver, but it's the same fundamental problem.
We're trying to call the usermode helper on resume at a time when it's disabled.
Comment 8 Alan Stern 2012-01-03 20:15:50 UTC 
Lars, can you trigger the problem again, but this time capture the output from dmesg either before or after suspending?  Attach that output to the bug report; it probably contains some clues to help explain what's going wrong.
