>Description:
	I get a panic while installing citrix_ica (all are typed in because crash still
	does not work here with raid on ahcisata).
	This is reproduceable.

uvm_fault(0xc0a10740, 0xfffff000, 1) -> 0xe
fatal page fault in supervisor mode
trap type 6 code 0 eip c0669cd7 cs 8 eflags 10213 cr2 fffffff8 ilevel 0
kernel: supervisor trap page fault, code=0
Stopped in pid 4861.1 (echo_cmd) at netbsd:linux_ioctl_socket+0x57: movl 0xfffffff8(%ebp),%esi

	There is no backtrace on cpu 1 where echo_cmd was running.
	cpu 0 has this backtrace (maybe because I was running the installation from another
	machine).

 Looks like NULL in %ebp? Would have been nice to know for sure what
 was in %ebp and %esp, because theoretically it should be hard to get
 null in there.

 Maybe mismatched use of -fomit-frame-pointer? Doesn't seem very likely...

 That fixed it for me with netbsd-5 where the line number were a little different.
