13 wherever you store normal kernel logs, so probably /var/log/messages but
14 if the GPF triggers in code that doesn't expect it, then the kernel may
15 as well be too toast to get that out into the filesystem. your best bet
16 is either a screenshot (digital camera, make sure you log as many line
17 as possible) or serial or netconsole. also make sure you enable kernel
18 symbols so the stacktrace is properly decoded.
