Public bug reported:
A user process crashed, and Linux switched from GUI to a text terminal, to show
the error message.
So I thought that was a kernel panic, and rebooted PC.
When that happened for a second time, I've just switched back to GUI mode by
pressing Alt-F7, and continued to use my PC.
So, it would be nice if kernel would print some clear instruction, like:
This is not a kernel panic. Dismiss this message by pressing Alt-F7.
Or, as an alternative, do not output any messages to kernel log when a
user process crashes, or other recoverable error happens.
The abusing process is the Adobe Flash player, and it crashes in a
rather bad way, by corrupting it's memory. Kernel does not print similar
debug messages for other crashed processes.
