After talking with kettenis@ I think the following diff is better. Starting with 0 jiffies should fix this issue. Unless we want to do the linux madness and set it to ((unsigned long)(unsigned int) (-300*HZ)) -- :wq Claudio Index: kern_clock.c =================================================================== RCS file: /cvs/src/sys/kern/kern_clock.c,v retrieving revision 1.109 diff -u -p -r1.109 kern_clock.c --- kern_clock.c 25 Jul 2023 18:16:19 -0000 1.109 +++ kern_clock.c 31 Jul 2023 20:01:57 -0000 @@ -84,7 +84,7 @@ int profhz; int profprocs; int ticks = INT_MAX - (15 * 60 * HZ); -volatile unsigned long jiffies = ULONG_MAX - (10 * 60 * HZ); +volatile unsigned long jiffies; /* * Initialize clock frequencies and start both clocks running.
