I've looked at the fix mentioned in previous PRs in clock.c, and it IS in fact in my source tree. symptoms: iostat yields outrageous numbers: tty wd0 cpu tin tout sps tps msps us ni sy in id 469665920197877836885994547262167552 0.0 0 0 0 0 0 systat -iostat reflects similar values systat -vmstat says: The alternate system clock has died! ... time rc5des -benchmark yields: ./rc5des -benchmark 0.00s user 30.47s system 98% cpu 30.833 total (this was mentioned in a previous PR, so I'll list the values here:) vmstat -i; sleep 2; vmstat -i reports: interrupt total rate clk0 irq0 32524987 99 pci irq10 1711156 5 fdc0 irq6 1 0 wdc0 irq14 6720130 20 wdc1 irq15 33855 0 sc0 irq1 115777 0 psm0 irq12 1316748 4 Total 42422654 130 interrupt total rate clk0 irq0 32525193 99 pci irq10 1711158 5 fdc0 irq6 1 0 wdc0 irq14 6720178 20 wdc1 irq15 33855 0 sc0 irq1 115778 0 psm0 irq12 1316748 4 Total 42422911 130 Also "top" no longer reports CPU percentages for ANYTHING: CPU states: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 0.0% idle (or any tasks) ----- As I mentioned above, this behavior is consistent, and I have been unable to isolate the conditions under which this behavior starts. To offset the effect, I have to do a cold restart, though sometimes the effect resumes almost immediately. >How-To-Repeat: Unknown -- though it's pretty sure the condition will occur eventually. >Fix: Not really a fix, but a temporary work around is to do a cold restart of the system. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
