hey folks.. Im running on a compaq proliant dual 733Mhz computer with 1 gig o memory.. I was running 5.4-STABLE a few weeks ago with no problem.. I did a make world about a week ago, and now I see lots of messages in syslog.. Aug 22 17:20:40 monsterjam kernel: calcru: runtime went backwards from 77810370 usec to 77203 321 usec for pid 48 (swi5: clock sio) Aug 22 17:20:40 monsterjam kernel: calcru: runtime went backwards from 17036511 usec to 16595 708 usec for pid 71 (schedcpu) Aug 22 17:20:40 monsterjam kernel: calcru: runtime went backwards from 77810370 usec to 77203 365 usec for pid 48 (swi5: clock sio) Aug 22 17:20:40 monsterjam kernel: calcru: runtime went backwards from 17036511 usec to 16595 708 usec for pid 71 (schedcpu) Aug 22 17:20:40 monsterjam kernel: calcru: runtime went backwards from 77810370 usec to 77203 463 usec for pid 48 (swi5: clock sio) and I see http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/troubleshoot.html#CALCRU-NEGATIVE but this info seems to only apply to 4.x. Is this really a problem? how can I squelch it? the other reason I ask is because ive had 2 HARD lockups since upgrading. I have since compiled a debugging kernel.. (in my kernel config) makeoptions DEBUG=-g options GDB options DDB options KDB (this look right?) I have a serial connection hooked up to this server and I cannot even break into the debugger when it hangs. regards, Jason
