Having got over the gcc 4.2 issue, I booted a seemingly good 2.6.22.1 kernel compiled with gcc 4.1.2. However, after starting a big (whole distro) compilation job (several make -j12 jobs in parallel), the machine begins to really slow down, eventually becoming unresponsive. I notice build jobs beginning to fail and my ssh connection is dropped. I managed to login directly from the ALOM console, and typed dmesg. Eventually, after a _long_ wait, I got the output below. This is a 2Gb machine with 2Gb of swap running a distro (<1Gb) out of initramfs. It has plenty of free ram at the start of the build (~1Gb) so it really shouldn't be invoking the oom-killer I suspect. Any clues as to what is going on? I can supply my .config if that will help.
