I 'solved' the Problem (?).

I followed a hint in one replies (above) to install FreeBSD 4.4-Release on a single Hardrive and the upgrade to 4.4-Stable (in my case 4.5-RC) because there have been some patches to the ata driver inbetween these releases.

I did it and when I reboot with a custom 4.5-RC kernel I can attach all four drives to the promise controller without hanging the system any longer.

Unfortunately I do not know what caused the problem in the first place (i.e. a buggy driver that got patched, or a bad system setup that got repaired by the improved ata driver ...) and feel a little alarmed.

BTW the driver works great.  It delivers some 37MByte per second to a single Hardrive --- writing to a ufs filesystem --- which is close to the limit of what the IBMs can support.  I was almost convinced that I should shun IDE for the rest of my life, unfortunately the ata drivers of FBSD developed a little to quickly.

Sincerely, Robert S.
