Carr --- I got another hang on kldload and this time ^T over the ssh session was responsive for about a minute, ending with load: 0.19 cmd: kldload 67182 [running] 53.73r 0.00u 0.01s 100% 1944k The process is using 100% CPU but none of it is counted towards user or sys= tem time. As I understand sched_4bsd.c and kern_clock, the percentage is based on what thread is saved in curthread when the clock ticks and may include time that= an ethical accounting system would not bill to the owner of the thread. "Note that we charge interrupts to the current process, regardless of whether they are ``for'' that process". --=20 You are receiving this mail because: You are the assignee for the bug.=
