[Bug 666305] [NEW] bug in 2.6.35-22 kernel, system not responsible, kthreadd

[Ipeacocks]

Public bug reported:

Binary package hint: linux-image-2.6.35-22-generic

I have noticed, that (or maybe) the ubuntu kernel 2.6.35-22 have some
nasty bug. Sometimes my system (kubuntu 10.10 x64) is not responsible.
In top i saw that process  jbd2/sda5-8 (it is а parent process of
kthreadd) strongly use my hdd. And I also saw that hdd led  lit
continuously. In 10.04 this bug was not observed.  I can repeat this,
when unplug power cable of my notebook. I also use cpu-freq but power
devil cannot manage by frequency of mobile cpu.
