This was based on 2.6.32-130 but had a additional patches including kdb. Jack Steiner thinks the patches are unrelated. Description of problem: I left a system (uvmid5) running last night. I _think_ Karl was running MPT regression but am not certain what else was running. When I woke up this AM, I noticed the system was in kdb. System was running a kernel I built from stout7/rhel6. Tree was current as of last night. <1>[ 4444.997462] BUG: unable to handle kernel NULL pointer dereference at 0000000000000038 <1>[ 4445.000851] IP: [<ffffffffa03211a8>] xs_tcp_setup_socket+0x318/0x470 [sunrpc] <4>[ 4445.000851] PGD 0 <0>[ 4445.000851] Oops: 0000 [#1] SMP <0>[ 4445.000851] last sysfs file: /sys/devices/system/node/possible [4]kdb> [4]kdb> bt Stack traceback for pid 4402 0xffff8802fcffe0c0 4402 2 1 4 R 0xffff8802fcffe750 *rpciod/4 sp ip Function (args) 0xffff8802fdfe9dd8 0xffffffffa03211a8 [sunrpc]xs_tcp_setup_socket+0x318 (0xffff88037cd13660) kdb_bb: address 0xffffe89e01907208 not recognised Using old style backtrace, unreliable with no arguments sp ip Function (args) 0xffff8802fdfe9dd8 0xffffffffa03211a8 [sunrpc]xs_tcp_setup_socket+0x318 0xffff8802fdfe9e30 0xffffffffa0320e90 [sunrpc]xs_tcp_setup_socket 0xffff8802fdfe9e58 0xffffffff81066ec6 worker_thread+0x136 0xffff8802fdfe9e90 0xffffffff8106b480 autoremove_wake_function 0xffff8802fdfe9ed0 0xffffffff81066d90 worker_thread 0xffff8802fdfe9ee8 0xffffffff8106b186 kthread+0x96 0xffff8802fdfe9f48 0xffffffff81003fca child_rip+0xa [4]kdb> ps 47 idle processes (state I) and 668 sleeping system daemon (state M) processes suppressed, use 'ps A' to see all.
