To: freebsd-hackers@freebsd.org Date: Sat, 14 Oct 1995 23:11:14 -0600 (MDT) X-Mailer: ELM [version 2.4 PL24] Content-Type: text Content-Length: 1017 Sender: owner-hackers@freebsd.org Precedence: bulk Hello, Occasionally, one of our servers die with a kernel trap 19: NMI ... going to debugger Kernel: type 19 trap, code=0 stopped at _copyout+0x35: repe movsl (%esi), %es: (%edi) The machine is a DEC 486, eisa bus, with 64mb RAM, having an isa adaptec 1542cf adapter. The operating system is the 950622 SNAP of 2.0.5. The system is unable to dump core and reports that the adapter is 'frozen?'. Trace from the debugger says: Bad user frame pointer: 0xefbfc0c0 The call was: _syscall (27, 27, 10, 80b4fc4, efbfc0c0) at _syscall+0x161 Any ideas ? What should I look for the next time it crashes ? Could this be a hardware problem ? The machine crashes about once every 7-10 days, with light load of users reading email and occasionally compiling small programs.
