I think this problem is now fixed. I was previously having problems with CPU lock-ups on my laptop (an HP Pavilion dm1-4020sa), and had fixed the problem by blacklisting the sp5100_tco driver, and disabling the thermal module (as discussed at https://bbs.archlinux.org/viewtopic.php?id=133541).
It seems that subsequent updates to the kernel have now fixed this CPU lock-up problem, and, in addition, the blacklisting of the driver and disabling of the thermal module was causing my most recent problems with failing to boot from grub from kernel 3.3.0-31 onwards. I have now removed the blacklisting of the sp5100_tco driver, and re- enabled the thermal module. I'm no longer getting the CPU lockups, and the new kernels are now successfully booting. So everything seems to be OK. Thanks to everyone who has helped looking in to this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1058969 Title: Kernel 3.2.0-31 fails to boot from grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1058969/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
