Nope. Like the previous issue it only happens when I run-time enable kernel modesetting (with # modprobe i915 modeset=1), which is not the default. I'm gonna open a new bz entry with all the details (and all the people on cc minus regression handlers). But first I'll check with CONFIG_LOCKDEP whether it's really a locking goof-up. -Daniel -- Daniel Vetter E-Mail: daniel.vet...@ffwll.ch Tel.: +41 (0)79 365 57 48 ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
