Re: [Bug #11516] severe performance degradation on x86_64 going from 2.6.26-rc9 -&gt; 2.6.27-rc5

Hi - 
Yes, this bug is still a problem with both the latest 2.6.27-rc6 kernel (from Linus' tree 2008-09-21)
and with the latest fedora 10 kernel .

CPU Frequency switching is completely disabled both when powernow-k8 (the correct cpufreq module for my
x86_64 AMD TL-64x2 2.2GHz CPU) is installed as a module or is built-in , and the CPU frequency remains
at its lowest setting; attempts to modify /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
and /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed are not honored, even though 
/sys/devices/system/cpu/cpu0/cpufreq/governor is "userspace" 
and scaling_min_freq < scaling_setspeed > scaling_max_freq .

I see no messages from powernow-k8 indicating that it is aware it was unable to set the speed, though
I do see a message if I attempt to set an invalid speed (eg 600000) .

With 2.6.26-rc9, I get a default CPU clock frequency of 2200000 ; with 2.6.27-rc6, it becomes 800000 and
is not switchable. For some reason, powernow-k8 does not autoload with UDEV; but I don't really need it if
the speed is already set to its highest level.

On 2.6.27-rc6. after it manages to boot, any low-latency drivers time out (eg. USB, Terminal, Keyboard,
Network) 
and the machine does not get through the boot-up sequence without becoming overloaded by the kernel's
debugging log messages -
neither the network , the terminal or the keyboard work usably. 

Building a kernel with USB completely disabled and turning off debug log messages allows the machine to
boot 
(after @ 15 minutes) but the speed is still at its lowest setting and cannot be changed.

Also, 2.6.27-rc6 is unable to reboot the machine: it can put the machine into the "HALT" state, with nothing displayed
on the screen, but the machine does not power-off until manual reset with the power-button. Then, after the machine

There are really multiple issues touched in report. nmi_watchdog
hangs, rtc device creation, NULL deref...

I've asked Joshua for more information. Since he must to use
netdev tree for a while maybe we could wait 'till next merge
window will be closed and check if nmi_watchdog does work.
So the work in progress.

The softlockup issue itself is fixed, but there are issues with
nmi_watchdog. I think we should remove the regression and keep the bug
alive to chase the other issues.

Well, for the sake of documentation I'd prefer to close this bug and create a
new non-regression one for the other issues if that's not a problem.

not sure if it should be;
From over here, I did a bad install
of isight-firmware-tools, causing hal and udev
to clash.  After making sure the package was either
using hal or udev, there is no message of disable irq #23.
If its not too much trouble is there a way to verify that this was
the case, i.g. if udev creates a dev, then hal creates the same device
will this cause ehci_hcd to have messages of this kind? If so

You didn't read what I wrote earlier, did you?  The "HC died" message 
should NEVER occur!  It doesn't matter what games you play with hal and 
udev -- it should NEVER occur.  Not ever.

And since the "HC died" is what causes IRQ #23 to be disabled, that 
shouldn't happen either.

appologize for not fully understanidng,
I'm just getting confused with why and what is causing this
to occur. The only reason for playing with hal and udev
is to have this message appear, if I leave them out of the picture
the system runs fine.
Anyways, I'm up to trying anything at this point, and again

The machine with these symptoms was sent in for service on Friday. I
suspect there may have been dodgy hardware involved on this one. I
think this bug should be closed for the time being. Once I get the
machine back, I'll reopen the bug if I can still reproduce it.

I'm unable to reproduce this on 2.6.27-rc7.  I don't think it has been
fixed, but I'm having a hard time finding a reliable way to trigger it

Thanks for the update.

For now, I'll close it as 'unreproducible'.  Please reopen if it happens again.

As I said in the bugzilla entry:

  Oops: 000b

  Bit 3 is set -- the processor detected 1's in reserved bits of the page directory.

That can't be good...

Re: 2.6.27-rc6-git6: Reported regressions from 2.6.26

Hi Rafael,
Correct patch is the one attached to bugzilla entry,
not the one you mention.

Alex.
