[mythtv-users] Crash on network transfer?

Thank you very much for the info - I'm going to try this out today when I
get back from my morning hike.

The keyboard lights don't flash when this happens.  When I was fussing
around putting in the new card yesterday, this is what I noticed in the logs
(attached).  I'll report back what I find later today.

Thanks for the help!

Chris

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 
          your disks. 


'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 
          console. 


'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 would 
          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 :-)
