My Thinkpad X40 (1.25 GB, ipw2200) has had fairly reliable swsusp since
2.6.13 or thereabouts, and as recently as 2.6.15-rc1-mm1 I had about 20
successful suspend/resume cycles. But now that I'm running
2.6.15-rc3-mm1 I'm seeing intermittent failures like this:

(The "suspend failed to assert current frequency..." messages have been
present since .14 or somesuch, and don't seem to have any deleterious
effects.)
This has happened 3 times so far, always on the second suspend after
boot. (boot, suspend, resume, suspend <fails>). Once it's failed I
have not managed to get it to succeed; attempting to suspend again
results in the same failure. But on my most recent boot I have not been
able to get it to fail through 4 suspend-resume cycles.
I suspend with a shell script that does
sudo sh -c 'echo shutdown > /sys/power/disk; echo disk > /sys/power/state'
On one of the failing cases I looked at memory usage and did not see
anything remarkable; there was about 400 MB free.
Full dmesg from failure below, and .config attached.

Thanks a lot for the report.
The problem is apparently caused by my recent patch intended to speed up
suspend. Could you please apply the appended debug patch, try to reproduce
the problem and send full dmesg output back to me?

You need at least count_data_pages() + 2*count_highmem_pages() free
pages (in lowmem).

Do you mean a separate page is needed for each kmalloc() in
save_highmem_zone()?

No, but notice get_zeroed_page() there, and that still needs to be
atomically copied.
So each higmem page takes:
1 get_zeroed_page()
1 kmalloc(struct(highmem_page))
+ copies of those into snapshot.

Here you go. This is two suspends; the first one completed
successfully, then I triggered a failure by starting a bunch of
processes until highmem looked full. (Just firefox wasn't enough, so I
started a bunch of vim -R sessions on a 50MB file until HighFree went
under 1MB.)

Yeah, right. I forgot to count them twice and I didn't take the kmalloc()s
into account. I'll do my best to produce a patch for it ASAP.
BTW, every kmalloc() in there seems to take 32 bytes (ie. the smallest generic
slab object size), which is a bit wasteful. The Andy's numbers indicate it
can take more than 700 pages just for that, and they have to be taken twice,
which gives more than 1400 pages total. It could be as little as about 300
pages _total_ if we did it more carefully. I think I'll place this on my todo
list for after 2.6.15.
Greetings,
Rafael

Well, now that's crystal clear.
I'm working on a patch.

Could you please apply the appended one and see if it fixes the issue?
It's on top of the previous one.
It's been compile-tested, but I have no machine with highmem to really
test it.

Well, still sizeof(kmalloc structures) ~= 1.3% of the real
data. That's not *that* bad overhad.

That's about 6MB more data to save on 400MB. Remember, I'm not
perfectionist (:-), and saving 1% more data to disk does not sound
_that_ bad to me.
Plus it only happens on highmem machines. Highmem is ugly hack, and is
going to die really soon, with 32-bit machines. I'd say it is not
worth fixing.
...I should not tell you, but swsusp is broken-by-design on highmem
machines. If you have 32GB highmem machine, under load, you'll
definitely run out of lowmem trying to swsusp it. Actually, you'll run
out of memory even on severely overloaded 2GB highmem machine
(attempting to swsusp). Fortunately noone knows, and noone cares.

Yep, this seems to fix the memory allocation failures at suspend.
Thanks!
(I have another separate issue with (I think) your swsusp changes, but
I'll start a new thread for it rather than extending this one.)
