Description

With a recent -2.7, I get this panic no more than 2 minutes after boot:

assertion: ref >= &td->td_toks_base && ref->tr_tok == tok in lwkt_reltoken

A core dump is available at this URL:

If this was related to a ^S/^Q on a tty or pty it has just now
been fixed.

I didn't have a chance to type these key sequences.

Howewer, most of the crashes occurred just after launching X, so it may
indeed have been related to a tty issue.

This is till happening.
System panics the very moment X tries to start on tty8.

A small update on this panic. It also happens when just switching between
virtual terminals with ALT+F(2,3,4,5 etc).

Ok, I'll try to reproduce w/ my workstation. I may be offline for
a bit :-)

These particular issues should now be resolved though I don't
guarantee that a few more cases are waiting in the wings.

No more troubles for me.

I must add that the GUI feels very fast now, much faster than 2.6 on the
same hardware. Latency must really have decreased with the latest mpsafe
commits.

Kudos !

It feels faster to me too on my workstation. I think a good chunk
of the reason is that the system isn't allowing held tokens to leak
across transitions to userland any more.
