I am a bit puzzled. I have tested up to 3.5.7 including the mainline 3.5.5, on which the quantal kernel is based, without encountering this error. But looking at the changelog I can't see anything related to drm or i915. Kernel 3.6.0 had the "light" version of the bug.
[ 9.001003] [drm:drm_pci_agp_init] *ERROR* Cannot initialize the agpgart module. [ 9.001046] DRM: Fill_in_dev failed. However X still works despite this error, while it does not in 3.5.0-17-generic. So I'm currently testing the 3.6-rc series to find the first ocurrence. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1070690 Title: BUG: unable to handle kernel NULL pointer dereference at (null); RIP: 0010:[<ffffffff8167f93a>] [<ffffffff8167f93a>] __mutex_lock_slowpath+0xaa/0x150 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1070690/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
