Yes, I am experiencing crashing and endlessly recursing GCCs when trying to build kernels on my 10V, on Debian armel, at least when compiling with multiple cores. With one core, I got a complete build (although this takes 4 hours then), at least after having the machine off for a day and then booting and starting to build directly. I also built a kernel in an armhf environment using 3-5 parallel jobs without a problem (in 2 hours build time). Furthermore, while building a kernel I tried to decompress a file; this failed on the first attempt, but succeeded on the second attempt. I ran some memory testing tools, but they did not find any problem. My questions here being: (a) do you run a customly built kernel? (b) do you use the binary nvidia driver? If I recall correctly, the builds only succeeded sofar on systems without binary drivers. But I can be wrong. -- Julian Andres Klode - Debian Developer, Ubuntu Member See http://wiki.debian.org/JulianAndresKlode and http://jak-linux.org/.
