Three Ubuntu 11.10 annoyances

A while back I posted up a few of the issues I was having with Ubuntu 10.04 “Lucid Lynx”.

I’m now using the latest version (for the next few weeks), Ubuntu 11.10 “Oneric Ocelot”. And while it works well on my new laptop, it suffers from three pretty annoying issues.

  1. IPv6 and Network Manager. I am experiencing regular wireless drop outs when I enable IPv6 on my router. When I disable IPv6 on Network Manager it is perfectly stable again.
  2. For most USB keys, write speeds are really slow. And I mean excruciatingly slow. USB HDDs seems to be OK. The issue seems to be in the way that Ubuntu deals with caching.
  3. Sandy Bridge power draining. This is a well known and documented issue, with fixes that have been issued (to be incorporated into the 3.3.x kernel). They are not being integrated into the current version of Ubuntu (which uses the 3.0.x kernel), but are being backported into the next version, 12.04 (which will use the 3.2.x kernel).

These things are quite frustrating, and while I am pretty confident that the power issues will be resolved, I really hope that the other problems are addressed for the next version which is due 26 April 2012. From those bug reports and blog posts, it looks like they will be, which is heartening.
