booting dual opteron system with windbg attached

I have a dual opteron mobo (Tyan thunder) and if I boot it with the
debugger attached, it seems to hang. If I boot it without the debugger
attached, it will boot fine and then I can attach the debugger later.
Unfortunately this means I can’t debug a driver as it starts from boot.
Any idea what could be wrong with this? I’m using windbg version 6.5.3.7
(it said 6.5.3.8 on the download page, but the title bar says 6.5.3.7).

Thanks,

Beverly

Some of the obvious questions first:

  1. Are you using serial or 1394 for the link?

  2. What if anything is displayed in the command window of the debugger?

I should add that I’m booting into 32-bit XP. I haven’t tried XP64 with
windbg yet.

I’m using a serial link (115200 baud). The debugger output windows gets
as far as “System uptime unavailable” and then it just stops. All the
usual stuff prints out up to that point. One thing that might be
interesting, though, is that it reports it as only one processor during
boot-time, but if I connect later it reports it properly as 2.

The usual cause of this kind of thing is Legacy USB support. I don’t
know if your target’s BIOS settings have an enable/disable for Legacy
USB, but if it does turn it off and the problem should go away.
