I have booted with this option half an hour ago and I started many instances of glxgears (10 exactly) and for this moment everything work perfect.
If I have any hang I will tell you.
May be I have found the problem...
I tried pci=routeirq as a boot parameter. glxgears ran at less than half normal speed and crashed the system when I closed it. Hope it is a fix for your system, but does not seem to be one for mine.
