As I said, it did not work. Efforts to make it work just started
recently, at a time when Suspend 2 already was stable and reliable to
me.
But, ok. Rawhide kernel 2.6.15-1.1955_FC5, which should be pretty close
to what Fedora Core 5 will have (Dave might know this better).
The first try was a desaster, partly my own fault, partly because swsusp
does not allow abortion (remember what I said about having a least some
basic stuff in the kernel). However, I rebooted, fscked, no filesystem
corruption *phew*.
The second try worked, with ugly messages scrolling over the console,
but ok, Suspend 2 already fixes some drivers which has not yet been
merged to mainline. The system resumed, which is fine.
Third try sound was gone. On the fourth try the system hanged after
starting ppracer (to test GLX/DRI on my i855).
This is a much more recent kernel, than the ones I used with Suspend 2
for the last 1.5 problems. Problems discovered have been no issue with
Suspend 2 for at least 7 or 8 months (no single crash or driver
problems). This is mostly a driver issue and undoubtly can be solved,
but I still do not see how this can be done when all efforts are put
into just another suspend implementation (uswsusp).
Ah, and now the part I really like, some hard numbers:
swsusp takes between 26 and 30 seconds to suspend (in my four tries: 26,
30, 28, 26) and between 35 and 45 seconds to resume (35, 45, 39, 37).
Suspend 2 does suspend in around 14-16 seconds, and resume in 18 to 21.
That is factor 2!

Matthias
