Hi,
the swsuspend mini howto says that a processor with pse/pse36 feature is
required for swsupend in 2.4.
The VIA Eden processor on my EPIA ME6000 board gives:
vdr:~ # cat /proc/cpuinfo
processor : 0
vendor_id : CentaurHauls
cpu family : 6
model : 7
model name : VIA Samuel 2
stepping : 3
cpu MHz : 599.731
cache size : 64 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu de tsc msr cx8 mtrr pge mmx 3dnow
bogomips : 1196.03
So I am obviously out of luck with 2.4 kernels, but what about 2.5 (the
mini-howto is silent here)?
Or are there alternatives to sw suspend for fast boot in this case
(preferred for 2.4 kernels as I do not have a 2.5 kernel tree and the
required infrastructure up to now)

There's really no requirement that you *need* PSE to be able to
do suspend, but it seems no-one has stepped forward to write the
necessary code to support non-PSE afaics.

I assume this is from a 2.5 kernel (I have no source tree available
here). I'll check that tomorrow in the office.

I don't even know what pse means :-(
Thank you

Same there. With some hacking, it may be possile to fix it.

If it is not in 2.4.X it only means 2.4.X will randomly flip bits in
memory during resume.

4MB pages, basically.
[Hey, this is great time to learn something new!]
