Fundamentally, that implies a bug in the kernel for your particular hardware.
Packages like uswsusp sometimes have more success because they apply
kludges/quirks to work around the bug. These kludges/quirks are better
handled in the kernel itself (sometimes hardware has quirks; other times it
is a software error).
Update, and this might need to go also into Debian Suspend/Resume wiki,
For suspend-resume, I've just discovered there's this bug notes in
A changes regarding skip saving of nvs state on suspend apparently
affected some systems. Affected system should be blacklisted in the
table by looking at dmidecode output.
My system, Sony Vaio VGN-SR26GN, is affected, the solution for me
currently is to add acpi_sleep=nonvs as boot parameter.
I've also attached my laptop's dmidecode output in there hopefully it
will be included in the blacklist table in the next round.
Hope it helps anyone else out there
Thanks all for the help and pointers.
All the best.
