Comment (by mmlr):

 Replying to [comment:4 kvdman]:
 > The log I did attach was of the failed second boot.

 I see. So it might not actually be interrupt issues but actual timeouts
 due to something hogging the system (interrupt storm, or actual delays
 caused by invalid MTRRs, or something else yet to be found).

 > Where are the settings for MTRR stored??

 Those aren't settings, they are runtime configurations constructed
 depending on the memory types the kernel and drivers register. As
 mentioned I don't see why they would differ from one boot to another
 unless the hardware changes. Maybe something's up though that causes some
 driver to behave differently on first boot, causing the MTRR setup to be
 different. A long shot though.

 > Is there a log file stored when running from LiveCD (CD boots every
 time)?

 At the usual place. The write_overlay makes the CD appear as writeable, so
 the syslog is written normally.

 > I did start the screen prefs app, but didn't change or adjust the
 resolution on any workspace.

 You could try not doing that once just to make sure, I wouldn't know off
 hand if the Screen prefs writes any settings if you only start it (I guess
 it doesn't).

 > The log was 475kb  uncompressed, so I thought it'd be more convenient to
 zip it. Now I know, thanks!

 Also, please don't add any vital information to your comments by editing
 them, because when reading the comments via the bug mails, which only
 contain the original comment, your info might just get lost... Just as
 another fun fact about ticket convenience ;-)
