Ubuntu 10.10 Performance issues with transmission or ktorrent indicator applet

[Noah Duffy]

Jon, I'm not exactly sure what would be causing the problem, but I know
that I used to have frequent drops of my Wireless connection under 10.04
and 10.10 that couldn't be resolved until I rebooted.  This has seemed
to stop under 10.04.  I wonder if the kernel has been patched under the
LTS release and not 10.10.  You may want to look into that.

Sorry I couldn't be of more help.

Thanks,
Noah
