Hello, I have a kernel with SW_WATCHDOG and simply enabled watchdog in rc.conf. I haven't found much info on that topic but I guess when the machine hangs (watchdogd doesn't get a result from the trivial fsck (what's that btw?)) the kernel will reset the machine. Best would be if I never see watchdog in action but I'm seeing a panic message after some interrupt statistics (see below) and the machine doesn't power off (like it does without watchdogd enabled). Any hints? I played a bit with setting the -t timeoutseconds but this didn't change anything, the machine doesn't power off. Is it correct that the trivials filesystem check of watchdogd is really done every second by default? Thanks a lot, -Harry Uptime: 25m6s interrupt total irq0: clk 771518 irq3: sio1 740 irq8: rtc 192856 irq10: fxp0 103 irq11: atapci1 21 irq12: fwohci0++ 69 irq13: npx0 1 irq14: ata0 51 irq15: ata1 17284 Total 982643 panic: watchdog timeout Uptime: 25m7s -------------- next part -------------- A non-text attachment was scrubbed...

Can you compare your experience with mine as described in PR 71800? http://www.freebsd.org/cgi/query-pr.cgi?pr=71800 I hadn't attributed this to the watchdog. I'll try that, but I have two boxes with watchdog enabled (FreeBSD 5.3 and 5.2.1) which don't exhibit any failure to shutdown, and I have two boxes with 5.3 that do exhibit (one ever since 5.3 BETA) the kernel IRQ messages on any type of shutdown. All have the watchdog on. Vivek Khera, Ph.D. +1-301-869-4449 x806
