Also note that alpha and ia64 machines can turn off unaligned traps, so that the kernel will kill off the process like it does on sparc. Unofficial Debian policy is that unaligned accesses are not allowed.Do you still actually see unaligned traps with recent hal? We fixed some of them some time ago. Also hal seems to work just fine on my SPARC, which suggest these problems have been fixed.
I don't have an alpha, and I don't run hal on my Ultra 5. I've never seen any problems, but I was trying to see if the submitter could solve the problems and at least tell us where the bug was. (If I could see them, I would have debugged them as far as I could.)
It is possible that an unaligned access only occurs on a subset of platforms, just because of the data layout in the binary. It's just my experience that when sparc tends to have unaligned access problems, they tend to be crippling.
If they're gone, then great. Just close the bug, and ignore my email. :-)
