Sorry about that.  I'll fix it up, but probably can't get to it until
Monday.  Hopefully that's an ok timeframe.

Cheers,
Jeff

Sure, not a problem IMO.

Andrew's patch works_for_me.  (Ack)


During the build, I got another (unrelated) build error:

kernel/built-in.o: In function `copy_process':
fork.c:(.text+0x162b6): undefined reference to `__node_random'
fork.c:(.text+0x162cd): undefined reference to `__node_random'

kernel/fork.c needs to #include <linux/nodemask.h>

[builds...]

But that is not enough.  The config file has CONFIG_CPUSETS=y
and CONFIG_NUMA=n, so __node_random() is not being built at all.

mmotm 2010-05-11 - dies in pm_qos_update_request()

Dell Latitude E6500, x86_64 kernel.

Died a horrid death at boot in the e1000e driver.  Seems to be
something in linux-next.patch. Didn't get a netconsole trace for obvious
reasons...

Copied-by-hand traceback:
pm_qos_update_request()+0x22
e1000_configure+0x478
e1000_open_device+0xee
? _raw_notifier_call_chain+0xf
__dev_open+0xec
dev_open+0x1b
netpoll_setup+0x28b
init_netconsole+0xbc

I suspect this commit:

commit 23606cf5d1192c2b17912cb2ef6e62f9b11de133
Author: Rafael J. Wysocki <rjw@sisk.pl>
Date:   Sun Mar 14 14:35:17 2010 +0000

    e1000e / PCI / PM: Add basic runtime PM support (rev. 4)

    Use the PCI runtime power management framework to add basic PCI
    runtime PM support to the e1000e driver.  Namely, make the driver
    suspend the device when the link is off and set it up for generating
    a wakeup event after the link has been detected again.  [This
    feature is disabled until the user space enables it with the help of
    the /sys/devices/.../power/contol device attribute.]

Not sure how to reconcile "this feature is disabled until" with my
traceback, since userspace hasn't even started when init_netconsole is
happening.

        /*
         * Enable early receives on supported devices, only takes effect when
         * packet size is equal or larger than the specified value (in 8 byte
         * units), e.g. using jumbo frames when setting to E1000_ERT_2048
         */
        if (adapter->flags & FLAG_HAS_ERT) {

How the heck did FLAG_HAS_ERT get set, we can't call pm_qos_update_request()
otherwise?

Aha.  Over in ich8lan.c, we have:

struct e1000_info e1000_ich9_info = {
        .mac                    = e1000_ich9lan,
        .flags                  = FLAG_HAS_JUMBO_FRAMES
                                  | FLAG_IS_ICH
                                  | FLAG_HAS_WOL

No, I don't think so.  I'm running -rc6 with this patch applied on a box with
e1000e and it works just fine.

Please try to revert this one instead:

Isn't a clean revert - build dies with:

  CC      net/mac80211/scan.o
net/mac80211/scan.c: In function 'ieee80211_scan_state_decision':

make: *** [net/mac80211/scan.o] Error 2

Will investigate more later, find what other commit needs reverting.

Simply rename pm_qos_request() to pm_qos_requirement() in
ieee80211_scan_state_decision() and it should build.

Confirming - reverting that patch and doing the build fixup results in a
kernel that doesn't blow up in the e1000e driver...

Dell Latitude E6500, x86_64 kernel.

Boots to single user prompt, but has issues on the way there.  Possibly
very important - I was definitely *not* typing at the time (as I had hit
return on the LUKS passphrase for the disk at 36 seconds after boot, and
I didn't get the # prompt for single-user for another minute or two (probably
due to udev having issues due to the oops). So I have no idea what it was

Udev probably tries to remap special keys on your keyboard...

Yes, it is likely. It may be caused by some bad conflict resolution between both git trees.
I'll handle this bug.

Ok. I probably won't have time for handing it until next week, as I'll be traveling

Then I guess there's an initializations problem somewhere.

Mark, any chance to look into that any time soon?  If we don't resolve this
before the merge window opens, I'm afraid I'll have to revert that commit
from my tree.

Can you try the tree at:

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6.git linux-next

without the other linux-next changes, please?

I'm not seeing the problem you're reporting on my test box with e1000e.
