I memtest86's overnight and came up with no errors on my one DIMM of Crucial Non-ECC, Non-parity PC2100 SDRAM (6464Z256). Updating, strace shows a hang on a /proc//stat read, as whown below. When run under strace, you can recover the terminal with Ctrl-C if and only if no strace log file is specified. I'd like to use ps, or better yet vmstat as test tools, since they reliable freeze. They are, unfortunately stripped binaries under SuSE 9.0. Can anyone tell me if there's an easy way to get the symbols file(s) for these executable(s)? Also, am I correct in thinking /boot/System.map will allow me to trace into the kernel?
