Hello,
The following just happened to me and I have no idea what caused it or whether something's totally wrong (I'm on a new laptop so I'm wondering whether it might be faulty hardware or something..) but some things look frightening, like:
[ 9776.420499] BUG: soft lockup - CPU#1 stuck for 61s! [gnome-system-mo:9731]
(full dmesg output below)
After writing some files to my external HDD, I unmounted, unhooked, and then started Vuze. The screen turned grey and although I managed to do a forced quit for the application, the whole system was messed up. Firefox, Epiphany, System Monitor, they all wouldn't start up anymore (actually the latter did nothing when I clicked it whereas the other two would freeze once the window had appeared). Fortunately, I could still get a terminal window and start gedit, so I was able to save the dmesg output. There was a whole bunch of stuff, but even with the help of Google I didn't manage to understand anything of what just happened :(
I'm particularly interested whether it has something to do with writing to an external (NTFS) HDD device, as this has given me some trouble in Ubuntu before (I'm hoping I can rule this link out, though).
Anyway, first, I wrote some files to an external (NTFS formatted) HDD device, which all seemed to go just fine:

Then, a few minutes later (didn't do anything in between), I started Vuze and that's when it all started to go wrong:

Eventually I had to do a hard reboot, as properly shutting down the system left me with a the just desktop image for a few minutes.
Does anyone know what 'java: Corrupted page table at address ...' (what is a 'page table' anyway?) and 'BUG: soft lockup - CPU#1 stuck for 61s! [gnome-system-mo:9731]' mean and whether any of the above could be related to writing to an external HDD or even faulty hardware (or just a buggy application)?
Any help or just a simple explanation of what dmesg is telling me would be very much appreciated! :)
(I'm running Jaunty with kernel 2.6.28-15)
The following just happened to me and I have no idea what caused it or whether something's totally wrong (I'm on a new laptop so I'm wondering whether it might be faulty hardware or something..) but some things look frightening, like:
[ 9776.420499] BUG: soft lockup - CPU#1 stuck for 61s! [gnome-system-mo:9731]
(full dmesg output below)
After writing some files to my external HDD, I unmounted, unhooked, and then started Vuze. The screen turned grey and although I managed to do a forced quit for the application, the whole system was messed up. Firefox, Epiphany, System Monitor, they all wouldn't start up anymore (actually the latter did nothing when I clicked it whereas the other two would freeze once the window had appeared). Fortunately, I could still get a terminal window and start gedit, so I was able to save the dmesg output. There was a whole bunch of stuff, but even with the help of Google I didn't manage to understand anything of what just happened :(
I'm particularly interested whether it has something to do with writing to an external (NTFS) HDD device, as this has given me some trouble in Ubuntu before (I'm hoping I can rule this link out, though).
Anyway, first, I wrote some files to an external (NTFS formatted) HDD device, which all seemed to go just fine:

Eventually I had to do a hard reboot, as properly shutting down the system left me with a the just desktop image for a few minutes.
Does anyone know what 'java: Corrupted page table at address ...' (what is a 'page table' anyway?) and 'BUG: soft lockup - CPU#1 stuck for 61s! [gnome-system-mo:9731]' mean and whether any of the above could be related to writing to an external HDD or even faulty hardware (or just a buggy application)?
Any help or just a simple explanation of what dmesg is telling me would be very much appreciated! :)
