Hi. Recently I switched to WITH_NEW_XORG, primarily because the stock X server
with Intel driver has some issues that make it unusable for me.
The new X server and Intel driver works extremely well, so kudos to whoever made
this possible.
Unfortunately, I am now experiencing random hangs on shutdown. On shutdown the
system randomly freezes after
[...] syslogd: exiting on signal 15
I would then expect to see 'Waiting (max 60 seconds) for system process 'XXX' to
stop messages, but these never arrive.
So it turns out that init hangs because vga_txtmouse (draw_txtmouse in fact) is
hogging the clock swi. The routine is waiting for a vertical retrace which never
arrives. (The new intel driver can't return to text console, so the screen just
goes blank when X exits.)
Some workarounds:
- don't run moused (i.e. disable it in rc.conf and devd.conf)
instead run the X server in combination with hald
- do run moused, but then either
- unplug the mouse before shutting down
- build a kernel with VGA_NO_FONT_LOADING
Of course the long-term fix is to remove the possibly infinite loop in
draw_txtmouse.
Thanks to Konstantin for his patience in helping me track this down.
Cheers
Michiel
