[-- Attachment #1 --] I discovered that on a 5.2-BETA SMP system I can cause Feb 8 18:29:32 <kern.crit> bento kernel: calcru: negative time of 6816 usec for pid 50286 (grep) Feb 8 18:29:41 <kern.crit> bento kernel: calcru: negative time of 7308 usec for pid 51007 (grep) Feb 8 18:30:41 <kern.crit> bento kernel: calcru: negative time of 6104 usec for pid 54944 (grep) Feb 8 18:30:42 <kern.crit> bento kernel: calcru: negative time of 5933 usec for pid 54962 (grep) by running a shell script that does lots of greps, and leaning on the ^T key in the shell to send the process lots of SIGINFOs.
