>Description:
	
While rsyncing 1.3 TB from an ufs file system to an lfs file system on same box, after around 200 MB:

db{0}> bt
Xintr_lapic_ipi() at netbsd:Xintr_lapic_ipi+0x7
--- interrupt ---
Bad frame pointer: 0xc3077318
0x30:

then, after rebooting and issueing save rsync command, after 392 GB:

sd5(isp0:0:21:0): unable to allocate scsipi_xfer

and nothing special in kernel messages; after this sd5 message, the computer is *very* slow, 

root@raidtest2:~# uptime
12:58AM  up  9:11, 2 users, load averages: 8.66, 8.59, 8.52                                                                                          
took around two minutes. Even typing 'uptime' on the serial console echoes around 1 char in two seconds.

Not production system, so I can test stuff.
