>Environment:

	133 Mhz Pentium on a SuperMicro motherboard with 512k PB cache.
32 MB EDO memory.  Adaptec 2940 SCSI controller with a 2GB and a 4GB disk.
Ethernet adapter, CD-ROM, etc.

>Description:

	Computer reboots frequently.  The computer is heavily loaded being
a server (and therefore more critical).  This is the only computer with
two disk drives with this configuration.  Other computers with a similar
configuration but less loaded and with only one drive do not reboot as
often.  With the previous release the problem was worse when the computer 
would hang instead of re booting.

	Pulling up the crash dump gives the following info

	IdlePTD 23f000
	Current pcb at 226c60
	panic vm_page_free: freeing busy page
	#0 0xf01b91cb in boot()


	Would like to know if this is a known problem and any other
information that is available.
