There seems to have been a flame war on this on LKML on what to do when the illegal situation arises. Alex's original patch was to BUG() when the problem occurs, got rejected, but Peter suggested to WARN() on the issue. Either should be fine to notify in syslog/console trace when the improper procedure to tear down the tty occurs.

Either way, it's still just instrumenting the bug. There still appears to be no true fixes are in sight. On June 25 LKML there was a message reply to the subject "BUG: tty: memory corruption through tty_release/tty_ldisc_release" that indicates the bug can also be triggered by having the link open and suspend/resume the machine (ouch).

I suppose it's just because not many people use BT else this would be a fairly serious bug...
