>Description:
	Starting Xsun causes the kernel to drop into the debugger with:
	  Stopped in pid 521.1 (Xsun) at netbsd:pmap_remove_pv+0x144

	Compiling a kernel with DEBUG causes:
	  data_access_error: tpc 13b724 == tnpc 13b724
	  data error type 32 sfsr=0 sfva=413f4004 asfr=104000000 afva=700000 tf=0x8287ed0
	with a ddb backtrace of:
	  data_access_error(8287ed0, 32, 700000, 104000000, 413f4004, 0)
	  ?(1, 1, 0, badcafe, badcafe, badcafe) at 0x1008e64)

	Repeatable on demand.  Happens every time Xsun starts (also tried
	Xsun from 2.0beta).  Might be related to PR sparc64/24126.

>How-To-Repeat:
	Run /usr/X11R6/bin/Xsun on Ultra1/cgsix

>Fix:
	Unknown.
