>Description:
seemingly random profile timer expired errors experienced after installing 4.2R on a previously functioning 4.1.1-Stable system.
This problem existed on 4.1R but disappeared after cvsup on 26-09-00
Other users had this problem...all had qlogic 1040 or 1080 scsi cards.
commenting out the psignal(p, SIGPROF); line in kern_clock.c seemed to help nsayer@quack.kfu.com. 
>How-To-Repeat:
install 4.1R or 4.2R and boot or try any long running process....delete a directory or cvsup or run  make buildworld...
>Fix:
