I have run the 'hibernate hang' (aka situation 1) quite a lot of times now, but only one time I managed to catch something with locatehang:
Looking for function that matches hash from the Magic Number from the kernel log. Magic: 2:752:371 maps to hash: 5a7cf2 Hash matches: __initcall_trace_init_flags_exit__recvfromearly() (address: ffffffff81b89340) Usually the hash does not match any know kernel function. Another phenomenem I noticed is that quite often when I power the machine on after the hard power-off, it boots up and when it is just about ready to show a login prompt it switches of and reboots. It seems to continue the last bit of the hibernation proces which it could not finish earlier (because of the hang and hard power-off) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/797922 Title: kernel hangs in pm-hibernate on saving to disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/797922/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
