Next: [loongson] add basic fuloong2f support
From: Nix on 5 Nov 2009 06:41
I'm not quite sure where to send these. LKML may not be interested 'cos
TuxOnIce is out-of-tree. The tuxonice list may not be interested because
these panics don't look like they're in the tuxonice code. It might be
an lzo compressor bug, or even a RAM fault intermittently revealed by
lzo compressor bugs yet oddly with not a single other symptom (somewhat
unlikely, perhaps, but e.g. full GCC bootstraps complete without
incident, which normally tease out *anything* of this nature in my
experience: so I'm assuming it's not bad RAM for now). I'm using Dave
Airlie's drm-next tree as well for kernel modesetting for my Radeon
HD4870, so I'm amazed things are working as well as they are :) (I must
say the Radeon KMS works wonderfully with not a single negative
consequence: bravo! It works well enough that I'm not even considering
it as a root cause of this yet, thus not Cc:ing Dave. I went through a
spate of compressor faults a month or so back, anyway, before I was
running KMS at all.)

(It might also be that the reserved pages overflowed this time around,
but I'd expect it to die at suspension time in that case, rather than at
resume time. The DRM code seems to want about 14000 reserved pages
normally: I've given it 20000, but maybe that isn't enough.)

(There are no obvious MAINTAINERS for the lzo code, but I'm Cc:ing its
original author of the lzo code anyway. Maybe this is all really
obvious.)

Still, I just got some panics on resume, logged courtesy of
netconsole. I tried a couple of times, getting a slightly different set
of recursive panics each time, but I think for the same reason. (The
system's a quad-core hyperthreaded Core i7 in 64-bit mode, so you never
know but that some sort of lethal race window might be missed the second
time around.)

..config attached, trimmed-down as usual by dropping comments and blank
lines.

The first panic, with a quite remarkably garbage task structure, probably
because that bit of the kernel state hadn't been read in yet, so the
oops printer oopses (not really very surprising):

Still a -22 compression fault at the core, but the call traces are quite different.

I'm going to try instrumenting the lzo code and add printks on error
(why aren't they there already?).

From: Nix on 5 Nov 2009 14:20
On 5 Nov 2009, Nigel Cunningham uttered the following:

>> It's odd that it manifested as a decompressor failure. I suppose if

Ew. Yeah, that would cause all *sorts* of problems :)

I just turned off all but one swap partition and did some hibernate/resume
rounds. The first four worked fine, but on the fifth, well, at the end of
the cache restoration phase (tuxonice_userui had kicked up and was at 100%),
it said

'Read of data failed --- press SPACE to continue'

and when I did so:

kernel panic: Read chunk returned (1)
Reboot in 5 seconds...

(followed by, uh, no reboot)

Different symptoms, not sure if it's a different bug.

Er, yeah, well, sort of. What I saw was that immediately after 'Atomic
copy/restore' (just after the screen flashes to black as KMS is
suspended), the progress bar flips back to zero: it briefly states
'Preparing image, try I' (which isn't something it says at the start of
the hibernate run), and restarts the hibernation process: upon
resumption the extra_pages count has risen (to 34613 in my case). I'm
not sure 'Preparing image, try I' really says what's going on, not least
since it's actually try II :)

(I had a strange failure a couple of days ago where it did that and then
the second atomic copy/restore basically soft-froze: the keyboard worked
and tuxonice_userui responded to keys like R and ESC by changing the
state of the screen, but it never left what it claimed was atomic
copy/restore and aborts of hibernation never came back to me. After ten
minutes I just turned the box off...)


It's peculiar, too. I suspect I ran out of extra pages in this case, so
it auto-restarted, but what I see in /sys/power/tuxonice/debug_info is

- Extra pages : 610 used/34613.

Now the kernel-configured extra page allowance is 20000, so it's plainly
boosted it... but to then use only 610 of them? Weird. I'm happy to
boost it (at least I am as long as these pages are only reserved during
hibernation), but still it's strange.
