[-- Attachment #1 --] We recently updated one of our dual Opteron systems (w/ 4GB RAM) from 5.5 to 6.2 (amd64 wipe and reinstalled) and about once a week, it panics with the below message: -=- TPTE at 0xffff8000040028a0 IS ZERO @ VA 800514000 panic: bad pte cpuid = 2 KDB: stack backtrace: panic() at 0xffffffff803fdd03 = panic+0x253 pmap_remove_pages() at 0xffffffff806072a3 = pmap_remove_pages+0x283 exec_new_vmspace() at 0xffffffff803e18e6 = exec_new_vmspace+0x216 exec_elf64_imgact() at 0xffffffff803cbb73 = exec_elf64_imgact+0x273 kern_execve() at 0xffffffff803e2107 = kern_execve+0x457 execve() at 0xffffffff803e2bed = execve+0x5d syscall() at 0xffffffff8060d141 = syscall+0x4d1 Xfast_syscall() at 0xffffffff805f8128 = Xfast_syscall+0xa8 --- syscall (59, FreeBSD ELF64, execve), rip = 0x80069838c, rsp = 0x7fffffffe7c8, rbp = 0x7fffffffecd0 --- Uptime: 4d16h55m46s -=- I do have a dump, and can make that available if need be. Has anyone encountered this recently and can shed any light on what might be causing this?
