# Wifi becomes incredibly slow after a few minutes of use (like, 1-2kb/s). This is a an Intel iwlagn 6250. I tried all kernels all the way to 3.2 with no improvement. The only workaround I could find is disabling 802.11n support.

+ # --My jWin Bluetooth headphones stop working when there's no sound output for about 30 seconds. After this, all applications that try to play some sound will hang until I disconnect the bluetooth device--

# My home is dm-crypt encrypted, alghough not with luks. After upgrading to Oneiric, it was no longer being mounted because mount thought it was of type minixfs. WTF?? To fix this, I had to pass '-n nominix' to blkid in /lib/cryptsetup/checks/un_blkid. This filtering was present in an earlier version of cryptsetup, but it has been removed in 2:1.1.3-1.
