I have created the Bugzilla entry at http://bugzilla.kernel.org/show_bug.cgi?id=10065 for this issue. Please add yourself to the CC list in there and update it with any new findings. > Also when compiling these many kernels via make -j4 I noted that I could > hardly move the mouse / use the keyboard, but saw random jumps and > key-repetitions... This last bit is most likely a scheduler issue. Do you have CONFIG_GROUP_SCHED set by chance? If you do, please try to unset it and see if that helps.
