>Description:
This problem has been found on both HP Compaq DL 380 and DL 385 with the Smart 
Array 6i controller. We first tried NetBSD 4.0 RELEASE i386/amd64, which gave 
the same symptoms.

Boot up the installation of NetBSD 4.99.72 (w/ "no APCI" enabled or disable), 
and during the installation (with progress) of the NetBSD base system the 
installer will show "- stalled -" instead of "xyz MiB/s". It usually happens 
after 79%+ of progress while installing (extracting via tar) the comp.tgz and 
xcomp.tgz packages.



>How-To-Repeat:
The general I/O performance against the disk(controller) is extremely slow. 
Extracting pkgsrc.tgz takes about an hour...
>Fix:
