[Bug 585765] Re: [HP ProBook 6440b] Ubuntu 10.04 random freezes


I am currently running 13.04 and the same problem is still present. It's
been with me since 12.04

But now I have discovered a pattern to these freezes: My power cord is
always unplugged when Ubuntu freezes.

I have a usage pattern that might have an impact: Whenever the screen
saver is starting (the desktop is fading out), I push shift or move my
mouse to avoid having to write the password. I know, it's odd behavior
since I could just prolong the timeout.

Clearly this has to do with power management, anyway.

Bug description:

  on my new laptop, a HP ProBook 6440b (with Core i5 and a plain Intel
  Chipset, 4GB RAM) I get randomly freezes of the whole system. I can't
  reproduce that, what means I don't know a aplication or usage of the
  system making it freeze. sometimes I have uptimes of a day, without
  freeze and sometimes it freezes right after booting the system.

  I found out, that sometimes the MagicSysRQ (R-E-I-S-U-B) works and let
  me shut down the system, sometimes not. I don't know what makes that
  difference. In the system log I can't find any unusual entries. But I
  foun that the system log is still runing, so shuting down the wifi
  with the notebooks hardware switch for example is logged. Also the
  Wifi network connection to my router is not interrupted.
