I see my minicom segfaulted for some reason (probably as I closed konsole window without exiting minicom first).

And I see this warning in dmesg - anything useful?

Looks like a very very old bug in the tty code. I have a patch for this I'm
testing for a while and will sort out properly after the kernel summit. In
the mean time have a play with the patch below which ought to do the trick.

Since I'm not able to trigger this issue any more (even without this patch), I won't be able to tell if this patch changed anything or not.

Could be good or not, depending on how you look at it...
