Nope, no messages from the bt or sd device drivers. No other kernel messages besides these. No system crashes happening either. > Sometimes RAM faults can cause these symptoms as well.

Meaning no SCSI errors spewed by the kernel and no problems using filesystems on them. Funny thing is the problem will happen for a few hours one day and than go for days without happening, and return, and then stop, etc. Thanks, Chris > > ... > > Oct 9 08:23:43 x /kernel: vnode_pager_input: I/O read error > > Oct 9 08:23:43 x /kernel: vm_fault: pager input (probably hardware) error, PID 14142 failure > > Oct 9 08:23:43 x /kernel: pid 14142 (in.nnrpd), uid 0: exited on signal 11 > > Oct 9 08:34:57 x /kernel: vnode_pager_input: I/O read error > > Oct 9 08:34:57 x /kernel: vm_fault: pager input (probably hardware) error, PID 17219 failure > > Oct 9 08:34:57 x /kernel: pid 17219 (in.nnrpd), uid 0: exited on signal 11 > > ...
