	ASUS P5A, BIOS 1011-beta, K6-2 500Mhz, Advansys ASC3150C rev B 
	SCSI adapter, HP CD-writer plus 9200 cdrw
	
>Description:
	System locks up when trying to burn CD with Advansys host adapter.
	Also locked once when trying to mount a CD that worked in the
	ATAPI CDROM.  Rebooted (after disabling aha driver in 
	/boot/device.hints - was trying a 1542 card).  Following reboot
	was able to mount a CD in the cdrw, but attempting to write
	consistently caused lockup.  cdrecord -blank appeared to work,
	but system froze as soon as write began.  ( Always hit the reset
	button with "0 of 243 megabytes written" on the screen. )

	Replaced Advansys card with an Adaptec 2940, and all is well.
>How-To-Repeat:
	Should be repeatable on a pristine 5.1R install with Advansys
	card.  The only changes made were adding pcm to kernel, and
	
	kern.timecounter.hardware=TSC

	to /etc/sysctl.conf to work around a clock speed doubling problem
	caused by ACPI.  Also enabled aha by commenting out the disabled=1
	line in /boot/device.hints and tried a 1542 card (system
	hung at boot - separate report) but restored device.hints to
	its original state.
>Fix:
	Unknown
