I recently added 4MB RAM to my machine (Intel 486dx2-66 ISA/VLB) taking it from 16MB to 20MB. It's running 2.2.2-RELEASE, and I compiled a new kernel with BOUNCE_BUFFERS enabled. Since then I seem to be getting a lot of bus errors. They occur mostly, but not only, when I try to login. If I manage to login I see from /var/log/messages that it's my login shell, tcsh, that's getting SIGBUS. I've also seen the C compiler terminate with SIGBUS, but it mainly seems to affect tcsh. I've also noticed that the bus errors occur more frequently once the machine has been up a few days. After a reboot I can usually login succesasfuly straight away, but after two or three days, I get SIGBUS on about 95% of all login attempts. What exactly is a bus error (as opposed to a segmentation fault), and why would I be getting so many of them now ? -- David Lay dave@netc.net.au
