xmon & SCSI ATA devices

[gshan]

Hello,

xmon and SCSI SATA device driver were installed on my system. When I invoked
xmon explicitly for kernel debugging, there're probably pending SCSI 
requests issued.
So those SCSI requests complained timeout when I quited from xmon. I want to
find a way to suspend SCSI device before invoking xmon and resume that 
before
quiting from xmon. Anybody knew there is a way to do this?

Thanks,
Gavin
