I've just changed from Ubuntu Studio to Linux Mint and wanted to use the real time kernel, as I get poor video performance with the generic kernel. I read elsewhere on these forums and simply did a "sudo apt-get install linux-image-rt", which installed it nicely and made the relevant entries in grub. So far so good.
After rebooting into the RT kernel, the first thing i noticed was the mintUpdate with a broken padlock. If I click on it & enter my password it works ok, at least until i reboot (this happens every time, but not with the Generic Kernel)
More seriously, after a period of minutes (everything works fine up to this point), the hard drive goes into melt down, and it takes 5 minutes to respond to a mouse click!
I've attached a screen shot from the "top" command, showing many pythons attacking the memory (which if you add it up its 152.5% memory usage ??), so i assume it's the swap causing a slow down.
I think it's mintUpdate thats triggering it, but don't know how to narrow down the problem any further.
I'm running this (Elyssa) as a guest in Vmware Player virtual machine, if any body would like to see if they can duplicate it.
(keep a terminal open with "killall -v python" just in case!)
Thanks in advance for any help provided.
