He's not running Prime95 (native Win32 app), he's running ports/math/mprime under FreeBSD natively. I don't know if this application stresses hardware to the same degree Prime95 does; I've used Prime95 many times to burn in new workstations. The Thinkpad hardware he's on is """old""" (note the quotes), so I wouldn't be surprised if the CPU (Intel Pentium M) happens to induce a strange/odd MCA event as a result of going in/out of sleep state. It could be a general system bug of some sort as well (one which has no repercussions). Look at it this way: if his L1 cache was going bad, his system would be freaking out doing literally anything (booting the kernel for example); I'm under the impression Pentium M CPUs do not have ECC L1 cache. -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
