BTLB address misaligned

Hi,

I'm trying to get OpenBSD working on a C110. Here's what happens:

Trying NetBSD gives a similar result (DTLB miss trap, I think). The
only thing I've found in (NetBSD) mailing list archives is that I
should pull out a few SIMMs. However, that's impossible in my case
since I only have two of them installed.

I've also tried booting Linux, with a ramdisk, which seems to work
fine.

Let me know if you need any more details.

What does ``BTLB address misaligned'' mean, anyway?


Thanks,

Alex
