SysReq & serial console

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I'm facing a similar issue like the thread

system keeps freezing once every 24 hours / random apps crashing

reported, but I still have to try all those suggestions.

For now, I've configured a serial console and enabled SysReq. When the freeze happens on my system, the system is still pingable and SysReq can for example sync the disks. I also can see on serial console which SysReq command I selected (registers, tasks, SAK, etc.), but I do not get any output of these commands on serial console.

When issuing such a SysReq command before the system freezes I can see the output of the command on a framebuffer console.

So, is it possible to redirect the output of a SysReq command to a serial console?
