Same symptoms as Lawrence Bezeau (see above). I have a HP Pavilion G4. I can get to GRUB, but the system locks up during the kernel boot, usually some time after the following message (although the specific time is never consistent):
shpchp 0000:00:01.0: Cannot reserve MMIO region SP5100 TCO timer: mmio address 0xb8fe00 already in use Bad LUN (0:1) Afterwhich, a hard reboot is necessary, ctrl+alt+f1 does not work. This occurred when I upgraded from 10.10 to 11.04. Incidentally, the 11.04 Live CD won't boot either. Going back to 10.10. Very frustrated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/577842 Title: shpchp cannot reserve mmio region -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
