mtrr: base(0xe0020000) is not aligned on a size(0x300000) boundary

Binary package hint: acpi-support

Suspend/resume has regressed badly on this ThinkPad X30 with current
Dapper (acpi-support 0.80). I'm not sure which version I was last
using successfully.

On a/c resuming after a suspend hangs with the display showing a
cursor and `inu' with the sleep light on. Only the power button works
at that stage.

On battery, resuming quickly causes another sleep. Pressing the
button again resumes, but with the display in inverse video, i.e. the
tty console is black on white and the X colours are all screwed.

Resuming after hibernating on a/c, it comes back, but stuff doesn't
work properly under X -- windows appear transparent and don't get
redrawn sensibly.

Debugging suggestions welcome.

I just noticed kernel messages like this apparently
both on suspend and resume, but I've no idea if
they're relevant.

I think the actual problem is with the X server; I think I remember reading something related to that message as part of trying to fix Xvideo problems after suspend.

Well something has definitely changed to cause trouble with the same
driver version that was previously working. It turns out I can fix
the problem with

SAVE_VBE_STATE=false

in /etc/default/acpi-support.
