I have just finished setting up my 2.2.8-STABLE box, and I just noticed an "interesting" bug. If one configures the rand_irq in rc.conf to be a reasonable-seeming set (the PCI bus 0 irq and some serial ports that only get used for UUCP), the system seems to become quite unstable, and panics fairly regularly (every few hours, but quite variable) with a stack trace very similar to: _generic_bcopy + 0x1a _comstart + 0xa6 _ttstart + 0x18 _siopoll + 0x175 splz_swi + 0x14 _add_timer_randomness + 0x1c2 _add_interrupt_randomness + 0x2d _Xfastintr3 + 0x17 I've returned the rand_irq setting to NO, and the problem seems to have gone away. Is this known, or should I do a little more characterization? It feels like a race between the timer update and another (say, serial) update of the pool doesn't play right, but I haven't even looked at the code yet.
