Subject: perf: perf_fuzzer triggers instant reboot
Date: Mon, 8 Sep 2014 13:47:11 -0400 (EDT)	[thread overview]
Message-ID: <alpine.DEB.2.11.1409081343270.29974@vincent-weaver-1.umelst.maine.edu> (raw)

Hello

so I finally had time to run my perf_fuzzer again and it has rapidly 
turned up an alarming crash that instant-reboots my core2 test machine.

This is on 3.17-rc4.  It is reproducible.

The first time all that appeared on the serial console was:

[ 2616.535995] Kernel panic - not syncing: Lost physical address for unconsumed uncorrectable error

The second time this happened instead:

[  756.009271] traps: perf_fuzzer[4236] trap invalid opcode ip:4044c0 sp:7fffb0ed6f90 error:0
[  756.017590] BUG: unable to handle kernel paging request

I'll work on trying to narrow this down a bit.

Vince
