How did it crash. Do the keyboard lights flash?
Change /etc/sysctl.conf, set kernel.sysreq to with this line:
kernel.sysreq = 1
this will set sysreq on during reboots. Do this to turn it on now
without a reboto:
echo 1 > /proc/sys/kernel/sysreq
Next time it happens try pressing one of these keys to see what is
happening. (I use p and t often)
'r' - Turns off keyboard raw mode and sets it to XLATE.
'k' - Secure Access Key (SAK) Kills all programs on the current virtual
console. NOTE: See important comments below in SAK section.
'b' - Will immediately reboot the system without syncing or unmounting
'o' - Will shut your system off (if configured and supported).
's' - Will attempt to sync all mounted filesystems.
'u' - Will attempt to remount all mounted filesystems read-only.
'p' - Will dump the current registers and flags to your console.
't' - Will dump a list of current tasks and their information to your
'm' - Will dump current memory info to your console.
'0'-'9' - Sets the console log level, controlling which kernel messages
will be printed to your console. ('0', for example would make
it so that only emergency messages like PANICs or OOPSes
make it to your console.)
'e' - Send a SIGTERM to all processes, except for init.
'i' - Send a SIGKILL to all processes, except for init.
'l' - Send a SIGKILL to all processes, INCLUDING init. (Your system
will be non-functional after this.)
'h' - Will display help ( actually any other key than those listed
above will display help. but 'h' is easy to remember :-)
