However, since you're using 2 proprietary kernel modules, you really ought to contact the vendors for those modules for support; they're a very likely cause for problems (for example, these two are the cause for the number 1, 2, 5 and 7 of the top 10 kernel oopses/crashes for the last week) > -- If you want to reach me at my work email, use arjan@linux.intel.com For development, discussion and tips for power savings, visit http://www.lesswatts.org
