I cannot install debian-amd64 on my Tyan based machine.
This problem looks like a previous one, posted here some weeks ago.
PROBLEM: instalation "freeze" after loading the scsi driver.
BUT: actually, I have succeded one installation (3 weeks ago); after
upgrading the system (and the kernel) some days ago, I could not reboot. So,
I decided to reinstall...When the system whas working (before I upgraded
it), it was also difficult to reboot the machine, with a lot of "retry"
of the scsi driver during the boot sequence.
