What does “freeze” mean? The display stays black, you cannot ping it, no
LEDs light up and you hear just the fans?

How reproducible is the freeze? Once a day?

Since it works sometimes, I believe quirks are not necessary. Also
nowadays quirks should not be needed anymore and pm-utils is not
actively developed anymore.

You have not told us yet what software stack you are running and a
link/overview of the hardware would be nice too.

1. My *guess* would be some issue with the graphics (driver) stack. You
could try to run with the VESA driver and test if this issue occurs with
that.

2. Anyway you should submit a bug report against the Linux kernel
package (`reportbug linux-image-…`), since the Kernel is responsible for
correct wake up as far as I know. Make sure to fill out the correct user
tags which is documented in the Wiki [1].

Make sure you supply useful logs. Is there something in
`/var/log/pm-suspend.log`?

3. You can test different versions of the software stack for example by
using live systems and test if this is a regression.

4. Have you seen reports from other 1015B users?

5. Try to use the netconsole of the Linux kernel and try to capture more
information.


Thanks,

Paul
