ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test3/2.6.0-test3-mm1 . Manfred might have fixed the long-standing task_struct use-after-free bug which happens occasionally on preemptible kernels. . This kernel immediately triplefaults when compiled with gcc-2.95.3 and CONFIG_KGDB. It is due to compiling with "-ggdb" or "-gdwarf-2". When compiled with "-g" it works OK, but gdb screws that up. Moral: use a later gcc if you're a kgdb user. . Lots of fixes for random things, as usual. Keep 'em coming.
