This has nothing to do with ewa0, dec550 ..irg too large(250) is
related to handeling of on-board USB ports.
The motherboard contains the last? update ECO's -no pyxis bug, and USB
ports. 'show config ' gives under ISA slot 0 device 8 USB .... I
switched to a Freebsd 4.2 HD to boot and get the enclosed dmesg. Can i
use isacfg command in SRM console to disable USB ports? Can i build a a
new kernel for booting this machine with a fix on the file(dec_550.c)?
-Mel
