I've been plagued by bus errors on my SS10 and U1E in the past whilst using Debian Etch. It appeared to be a bug in the domain name => IP code - which caused all the stuff I wanted to run on it to immediately fail. What notes I could find on bus errors on Sparc led me to believe that this error was caused by unaligned memory accesses. (please correct me if I'm talking out of my arse) I guessed that the problem was somewhere in libc. (and hence inaccessible for me) The problems all went away when I upgraded the boxes to the new version of libc in Lenny. (before Sparc32 support was dropped) I'm guessing that something in erlc is doing a cast when it should do a memcopy. However I've never even tried to get to the bottom of this on my boxes, and given that the U1E now works fine, I've never had any reason to.
