PROBLEM: Kernel oops in kmalloc (network?) - 2.4.3-ac7
Hi I just got an oops with 2.4.3-ac7: [1.] Kernel oops'es and KDE hangs. [2.] While compiling gcc, suddenly KDE hangs. I was able to change to a console to investigate the problem. It appears that the dying process was kwin as X and other parts of KDE still is responsive. The kernel seems to run happily on after the oops.
