[Bug 1301245] Re: System unresponsive under (IO/memory?) load
$ uname -a
Linux lptp 3.14.0-031400-generic #201403310035 SMP Mon Mar 31 04:36:23 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
seems to work much better.
I still get occasional lags (processes slow to start, thundebird laggy,
brief mouse cursor freezes) when I try to untar an 80G backup tarball
but the system feels more responsive than before. I cannot say if the
problem is actually fixed in the mainline kernel or if it is just my
impression, or if the system works better simply because it has just
been restarted.
I will use this kernel for a while and try to sleep/resume it several
times. If I spot any issues I will report them back here.

Title:
System unresponsive under (IO/memory?) load
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Tasks producing a lot of IO activity and/or use large amount of memory
(uncompressing a .tar.gz file, starting a VM in virtualbox) starve the
rest of the system. The system is responding to user input very slowly
(jerky mouse pointer movement with >1s intervals etc). I have not seen
that issue on previous Ubuntu versions, this is the first time I use a
64 bit system with full disk encryption.
64bit Xubuntu 13.10. Full disk encryption. 4GB memory. Sony Vaio
laptop. Same behavior observed with Nouveau and NVidia drivers.
