I am running the ltp tests. Status is always 9001f003 and the cause is always 00002000. epc always points to 80014570 which is in: ffffffff8001451c T pgd_init ffffffff80014560 T update_mmu_cache <------------ ffffffff800146d0 T show_regs Sometimes my kernel reboots and sometimes it continues on. I get the error when compiling and also when doing make clean. So just about anything will make it happen make[4]: Entering directory `/opt/ltp/testcases/kernel/syscalls/getpgrp' cc -o getpgrp01 getpgrp01.c -I../../../../include -L../../../../lib -lltpGot reserved at 80014570. $0 : 00000000 2ab042cc 81f83ca0 81f83ca0 $4 : 81a23720 2aaae734 2aaae734 00000000 $8 : 802a3510 1000001f 6ffffdff 70000053 $12: 6fffffff 00000063 2ab04268 7fff7510 $16: 8107d6c0 ffffffff 81a23720 81f86260 $20: 81e23ab8 2aaae734 81f83ca0 00000000 $24: 00000000 2aaae734 $28: 812f6000 812f7df8 7fff7420 8002a19c epc : 80014570 Status: 9001f003 Cause : 00002000 Kernel panic: Caught reserved exception - should not happen.
