Subject: 2.6.39-rc1 noveau trouble and regression (bad commit: 38f1cff0863809587b5fd10ecd0c24c8b543a48c )

Hey,

After bisecting for a day, I'm pretty confident that the commit
38f1cff0863809587b5fd10ecd0c24c8b543a48c introduced an error which
causes one of my computers to hang during boot -- only a blank
screen appears. The initramfs never gets run.

The system consists of an Atom D525 with Intel NM10 + NVIDIA GT218/ION2
chipset.

Best,
Dominik

Hey,

still no joy with 2.6.39-rc2.

Best,

Subject: 2.6.39-rc1 nouveau regression (bisected)

Thought about CCing Linus to show him that 2.6.39-rcX isn't as "calm"
to everyone, but then chose to CC Maciej instead: Would you be so kind and
add this to your regression list? Thanks!

Since commit 38f1cff

Subject: [PATCH] Merge commit '5359533801e3dd3abca5b7d3d985b0b33fd9fe8b' into dr

This commit changed an internal radeon structure, that meant a new driver
in -next had to be fixed up, merge in the commit and fix up the driver.

Also fixes a trivial nouveau merge.

Conflicts:
drivers/gpu/drm/nouveau/nouveau_mem.c

booting my atom/NM10/ION2 system crashes hard during boot, right after
blanking the screen, and before the initramfs gets loaded. I just
re-checked: both parent commits ( 5359533 and 4819d2e ) do indeed work
just fine, but the merge commit ( 38f1cff ) fails, same as tip ( 85f2e68 ).

My previous reports (Apr 03, Apr 07) seem to have gotten lost (or ignored,
or both).

Best,
Dominik

Can you activate netconsole and check whether kernel spits anything interesting?
You might try to load nouveau module after boot - maybe something will be saved
to /var/log or you could even ssh into the box and check dmesg...

Compiling it as a module seems to work fine. When I do so, no regression is
obvious from what gets reported in "dmesg". However, somehow I now do get
some output: The last message I see is

[drm] nouveau 0000:01:00.0: allocated 1680x1050, fb 0x40.... b0 <some pointer value>

Then, nothing more. However, it really is quite strange why this error only
appears in the CONFIG_NOUVEAU=y case, not in the =m case...

Dominik

Try disabling CONFIG_BOOT_LOGO. I reported on freedesktop.org that it is
causing me an oops at boot, but my bug has been ignored there so far -
perhaps I should have posted it here instead.

I'm getting the exact same symptoms on my Atom + ION hardware. Crashes before it
can write any logs if it's compiled in and the logo is selected, but boots fine
if compiled as a module or the logo is removed.

In my case I bisected and found 8969960 by Nick Piggin (change to mm/vmalloc.c)
to be the first bad one in 2.6.38+. This makes me think that it's not a bug in
nouveau, but maybe a bug in the order that things are initialized?

Config below. (It boots as is, but if you enable CONFIG_LOGO it won't.)

FWIW, reverting commit 89699605fe7cfd8611900346f61cb6cbf179b10a on 2.6.39-rc3+
makes my system boot just fine with the nouveau drivers compiled into the
kernel. I've seen some similar looking bugs on LKML that this regression may or
may not be related to? It works fine on 2.6.38.

https://bugzilla.kernel.org/show_bug.cgi?id=33272
http://lkml.org/lkml/2011/4/15/194

I'm still trying to figure out exactly where the kernel is crashing after
printing
[drm] nouveau 0000:03:00.0: allocated 1280x1024 fb: 0x40000000, b0 f4cf7600

Any thoughts on what else I should look for?

I reproduced this bug today, and reverting 89699605fe7cfd8611900346f61cb6cbf179b10a
does not fix it for me. Here's the backtrace:

Looks like your kernel is getting farther along than mine. I get a hard freeze
with no oops though. From what I can tell mine is also following the same path
through the fb_notifier stuff just before crashing. Can you "fix" your kernel by
changing nouveau to be a module or turning off the tux boot logo?

I reproduced this bug today, and reverting 89699605fe7cfd8611900346f61cb6cbf179b10a
does not fix it for me. Here's the backtrace:

It crashes on:
nouveau_bo_wr32(chan->notifier_bo, chan->m2mf_ntfy + 3, 0xffffffff);
in nouveau_fbcon_sync.

Well, to get this trace I had to enable netconsole, patch nouveau[1] to load after
netconsole initialisation and enable kgdb.

Yes, changing nouveau to module and disabling logo "fixes" it too.

indeed, setting CONFIG_LOGO=n makes it boot. Same as compiling nouveau as a
module. With all the different bisect results and reverts which make it
work, it seems to me to be a timing / interference issue...

Looks like something wrote 0xffffffff to free'd memory.

Enabling DEBUG_PAGEALLOC *might* show where it happens.

So here the 0xffffffff is pretty obvious.

Here it is less obvious, but it was _probably_ a regular kernel
pointer of the type 0xffff8801bc70b058 before the high bits were
overwritten by a 0xffffffff.

So then sysfs_refresh_inode() follows that pointer, and crashes.

Just a guess, obviously, but it looks rather likely.

Thanks. It helped a bit.
I'll send two patches in response to this message, one of which fixes this bug.

Subject: [PATCH 1/2] drm/nouveau: fix notifier memory corruption bug

nouveau_bo_wr32 expects offset to be in words, but we pass value in bytes,
so after commit 73412c3854c877e5f37ad944ee8977addde4d35a ("drm/nouveau: allocate
kernel's notifier object at end of block") we started to overwrite some memory
after notifier buffer object (previously m2mf_ntfy was always 0, so it didn't
matter it was a value in bytes).

to be off by -16 bytes. Fix it.
