>Description:
When having problems with microuptime going backwards, the symptoms look worse due to a typo in the debug message. Instead of a period, the second time is printed with a comma (in /usr/src/sys/kern/kern_synch.c). For example:

Dec 31 23:01:37 xanadu /kernel: microuptime() went backwards (688450.094451 -> 688450,-695028036)
Dec 31 23:01:37 xanadu /kernel: microuptime() went backwards (6884ckwards (688451.905274 -> 688451,885155)
Dec 31 23:01:37 xanadu /kernel: microuptime() went backwards (688451.905274 -> 688451,899963)
Dec 31 23:01:37 xanadu /kernel: microuptime() went backwards (688451.942972 -> 688451,923447)


Also note that there is at least one other bug resulting in a negative usec value, probably subtracting when it should be adding, that I was not able to find.
This comma has been a problem since 4.0 and still exists in 4.2.

Sorry, I don't know how to do a useful diff.
