3.4.0-02580-g72c04af regression on sparc64 - partitions not recognized

Just tested 3.4.0-02580-g72c04af on about 10 machines. While most of
them work (including 3 different sparc64 machines with real scsi disks),
Sun Netra X1 with pata_ali and IDE disk consistently fails to boot. sda
is recognized but no partitions. 3.3.0 works fine, as did something
around 3.4-rc7 (plain 3.4 not tested yet). No other IDE machines tested
yet since I have none with remote console at the moment.

# fdisk -l /dev/sda

Disk /dev/sda (Sun disk label): 255 heads, 63 sectors, 14596 cylinders
Units = sectors of 1 * 512 bytes

Device Flag Start End Blocks Id System
/dev/sda1 0 192780 96390 1 Boot
/dev/sda2 192780 13864095 6835657+ 83 Linux native
/dev/sda3 0 234484740 117242370 5 Whole disk
/dev/sda4 13864095 19856340 2996122+ 82 Linux swap
/dev/sda5 19856340 234484740 107314200 83 Linux native

First 512 bytes of the disk:

3.4-rc7 until 72c04af is about 3500 changes, we'll need to narrow this
down further.

I would first check to make sure that 3.4.0-final doesn't have the
problem.

If 3.4.0-final is OK, start bisecting from v3.4.0 until 72c04af. One
possibility could be the sparc64 NOBOOTMEM conversion that went into
the merge window.

Meanwhile tested that 3.4 was OK and started bisecting. It will take
time because I can access the system only some iterations per day.

Bisecting leads to this commit:

a7a20d103994fd760766e6c9d494daa569cbfe06 is the first bad commit

[SCSI] sd: limit the scope of the async probe domain

sd injects and synchronizes probe work on the global kernel-wide domain.
This runs into conflict with PM that wants to perform resume actions in
async context:

Does reverting just the part of the commit that touches scsi_lib.c make
any difference?

If not, does leaving that part in and reverting all the rest of the
commit make any difference?

My theory is that this is an init problem: The assumption in a lot of
our code is that async_synchronize_full() waits for everything ... even
the domain specific async schedules, which isn't true.

The code in init that makes this assumption is wait_for_device_probe().
There's also a fun async_synchronize_full() in init_post() that assumes
it can free the init memory after, which would fail badly if anything in
init used an async domain.

So either we fix the assumptions or we can't use domain specific async
schedules.

Hm, we already have cases of code not trusting the semantics of
wait_for_device_probe(), especially as it relates to async scanning like
in kernel/power/hibernate.c:

/*
* Some device discovery might still be in progress; we need
* to wait for this to finish.
*/
wait_for_device_probe();

if (resume_wait) {
while ((swsusp_resume_device = name_to_dev_t(resume_file)) == 0)
msleep(10);
async_synchronize_full();
}

/*
* We can't depend on SCSI devices being available after loading
* one of their modules until scsi_complete_async_scans() is
* called and the resume device usually is a SCSI one.
*/
scsi_complete_async_scans();

This is actually looks wrong: it works if SCSI is built in, but it's a
nop if SCSI is a module (the nop function is gated by the else clause of
#ifdef CONFIG_SCSI)

Rafael, you added this not via the SCSI tree, is that the intention?

But this still doesn't fix the boot problem, does it? ... unless we want
to add a scsi_complete_async_scans() into init/do_mounts.c, which looks
like piling one hack on top of another.

I really think the correct fix is to have wait_for_device_probe()
actually wait until all probes have completed and everything is
discovered, that way we get the semantics the name implies and boot
should just work.

I managed to convince myself that one in prepare_namespace() was
probably not needed because of the late_initcall of
scsi_complete_async_scans() in the built-in case and in the module
case the initramfs should be taking care of it.

...but wouldn't it need to go something like:

wait_for_device_probe(); /* all pci drivers probed */
scsi_complete_async_scans(): /* flush host scans */
wait_for_device_probe(); /* all recently attached sd devices probed */

?

Ah, now I remember, that was the hack we put in to prevent a boot panic
caused by a similar thing ... mainly because async SCSI scanning uses a
custom infrastructure.

No .. the point is if we wait for all outstanding scans instead of just
those in the async_running domain, it will "just work", with no special
SCSI magic.

That's correct, it was committed directly by Linus.

Pretty much it is.

The code snippet is slightly out of context and it is a part of the
software_resume() routine, which is only called when the kernel's built-in
image reading code checks whether or not the image is present. It won't
work anyway if SCSI is not built in.

I don't understand this.

Why would it make a difference whether SCSI is modular at hybernation
resume time? The reason it makes a difference at boot time is because
there's no initrd to wait for the scans and mount the root if we're not
modular, so the init path has to do it. However, when resuming an
image, the module is already loaded into that image, so there should be
no difference at all between steps taken in the modular and non-modular
cases.

Just finished testing it against 3.4.0-05722-gf936991. Without the
patch, this version fails to boot and with it, it boots fine. Now going
to test your 4-patch series.

I think Rafael is referring to the boot kernel -- the one that reads in
the hibernation image initially. Whether or not the boot kernel can
have modular drivers isn't clear to me; I don't know when the check for
a valid image in the swap area is carried out in relation to starting
up the initramfs task.

That's correct.

> Whether or not the boot kernel can have modular drivers isn't clear to me;

It can, but then the code in question is irrelevant and the resume has to
be triggered in a different way. For example, by writing to
/sys/power/resume from the initrd boot scripts.

This particular one is carried out before the initrd is loaded.

I just got hit by this one too, but on x86 qemu. There's no initrd, and all
the modules are built in.

With commit a7a20d103994fd760766e6c9d494daa569cbfe06 the kernel doesn't
get to the point where it reads the partition table.

If it's of any help, I can provide more details.

Yes, please send the qemu config details.

Inline below. I've also included some more info before that just in
