Comment 144 for bug 355155

The freezes began for me immediately after upgrading converting my partitions from Ext3 to Ext4, but after speaking with other people in the Ubuntu forums, that seems to be more of a coincidence than a cause. Unfortunately, I picked a bad time to start using Ext4 since Ubuntu/Kubuntu's instability has meant data loss. Most of my freezes happen when I open Ktorrent, but it's not a consistent problem and isn't limited to Ktorrent. Yesterday I had a freeze while reading a web page in Firefox.

Transitioning back to Intrepid is too time-consuming. I am swamped with work right now so I don't have the time to do it and I don't have the time to keep dealing with these freezes when I should be working. If I'm going to take the time to reinstall the OS, I'm going to install Debian or something more stable or at least a distro where bugs like this are high priority. I've been using Kubuntu for more than 2 years (since Edgy) without a reinstall so if I'm going to do one I'm doing so with the expectation that I'm in for the long haul with the distro. And this current mess does not give me much faith for future Ubuntu releases.
