To add more information to this. If I start Lyx on its own (i.e. just 'lyx' at the command line, no file selected), then it starts fine. However if I then try to open a file I get the same behaviour as above. The above was triggered when doing 'lyx somefile.lyx' at the command line. This is probably not useful, but thought I would mention it.
Next I installed linux- image-3.2.14-030214-generic_3.2.14-030214.201204021356_amd64.deb, rebooted into that kernel and got a similar error (see attached oops). I then install linux- image-3.2.15-030215-generic_3.2.15-030215.201204131303_amd64.deb and rebooted. This time the machine wouldn't come up. Choosing recovery mode in the Grub menu so I could see the kernel output, there were a couple of BUG/OOPS messages (the top scrolled of the screen so I couldn't see all of it). It appeared to be related to module loading/unloading. I was then left with some repeating udev messages about timeouts trying to do modprobes (I didn't write down the exact message). This seems unlrelated to this bug. As an interesting footnote, while I was editing the attached oops message in gedit, as I saved it into my homedir the same bug was triggered again, causing gedit to hang. Luckly it had actually written the file and I could access it fine. ** Attachment added: "3.2.14-generic.oops" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/981278/+attachment/3068423/+files/3.2.14-generic.oops ** Tags removed: needs-upstream-testing ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/981278 Title: Kernel Oops - BUG: unable to handle kernel paging request at ffffffffffffffb8; RIP: 0010:[<ffffffffa013e839>] [<ffffffffa013e839>] nfs_have_delegation+0x9/0x40 [nfs] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/981278/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
