>Description:

	After installing wip/tsm (IBM Tivoli Storage Manager backup
	client, linux binary) I started the cli tool dsmc, and got

kernel: supervisor trap integer divide fault, code=0
Stopped in pid 24176.1 (dsmc) at        netbsd:__qdivrem+0x38:  divl    %ecx,%eax

and then the box hung, so no coredump.

The machine is a
cpu0: AMD Dual-Core Opteron or Athlon 64 X2 (686-class), 1795.66 MHz, id 0x20f32
cpu0: "Dual Core AMD Opteron(tm) Processor 165"
running NetBSD/i386.

wip/tsm has been used in production on two netbsd-3 machines here for
quite a while, without any problems.

>How-To-Repeat:
	Install netbsd-4, then wip/tsm. Start dsmc, try to log in to TSM server.

>Fix:
	Don't use TSM?
