[ltp] Question about swsusp and ACPI-related errors in the log (kernel 2.6.8.1 on a T41p)

[François Fleuret]

Hi,

So far, I have been using the S3 suspend on my T41p. With the kernel
2.6.8.1 and the acpi patch, it works perfectly (except the errors
described below, but no problem in the behavior of the PC).

I am now starting to think about the swsusp to avoid the power
consumption of the S3. My distribution is Debian, and I have a hard
time simply finding the binaries of swsusp or swsusp2. Can somebody
summarize quickly what are the steps to get it working ? Kernel patch
? Binaries ? What are the differences between swsusp and swsusp2 ?

Also, I have in /var/log/message lot of lines like:

What the is that ? Is that serious ?

Thanks in advance for any information.
