Hi,
running raidctl -c on current with debug options I get:
panic: kernel diagnostic assertion "(l) == curlwp" failed: file "/dsk/l1/misc/bouyer/current/src/sys/dev/dksubr.c", line 640
Stopped in pid 8.1 (raidctl) at netbsd:breakpoint+0x1:  ret

vn_ioctl() at netbsd:vn_ioctl+0x79
sys_ioctl() at netbsd:sys_ioctl+0x1bc
syscall() at netbsd:syscall+0xe5

Reading the code I understand why we get a panic (rf_ConfigureDisk pass
raidPtr->engine_thread to dk_lookup()), the question is what would be
the fix ...
