>Description:

The following anita command (pkgsrc/misc/py-anita) runs out of disk space
and then imediately fails a kernel assertion:

anita --memory-size 256M --disk-size 500M --workdir ./workdir test 
http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201109140130Z/amd64/

Unfortunately no backtrace. The assertion is:

kernel diagnostic assertion "uvm_page_locked_p(pg)" failed: file 
"/home/builds/ab/HEAD/src/sys/arch/x86/x86/pmap.c", line 3214
