This problem is only on my EEE. desktop computer bootup well.

CURRENT about 15th may 2009 boot well from flash drive. But it's too old :)

You can set kern.cam.boot_delay=4 in /boot/loader.conf in order to boot.

I've tried up set this value up to 10-15. This is not work. I also
tryed put this option in defaults/loader.conf to test

Which latest world doesn't have this issue?

It may be in milliseconds, try 4000.

Obviously, it doesn't work. I've found patch in same issue kern/144824
but it doesn't work also :(

Grep finds this tunable int in xpt(4) device, not in da(4) or pass(4).

[Paul B Mahol]

10000 in my case works.

Wow! It woks! Thanks for this workaround!
