- sky2: dont enable PME legacy mode
-
- This bit is not changed by vendor driver, and should be left alone.
- The documentation implies this a debug bit.
- 0 = WAKE# only asserted when VMAIN not available
- 1 = WAKE# is depend on wake events and independent of VMAIN.

-The RCU problem is likely to be a separate issue. It might even be a
-result of the use-after-free problem with the elevator.
-
-At any rate, it's clear that the crash in the refcounting log you

-scsi_prep_state_check(), which tried to dereference the NULL pointer.

-While I was playing with 'xm vcpu-set X N' I realized that the VCPU hotplug
-code in 3.2 spews tons of messages. Found out that we were missing an preempt_*
-call. While at it, I fixed also an annoying message ("XENBUS: Unable to ..")
-that shows up during bootup.

-Date: Wed, 1 Feb 2012 16:16:39 -0500
-
-When a user offlines a VCPU and then onlines it, we get:
-
-NMI watchdog disabled (cpu2): hardware events not enabled

- [<ffffffff810349be>] cpu_idle+0xbe/0xe0
- [<ffffffff81583599>] cpu_bringup_and_idle+0xe/0x10
-
-The reason for this should be obvious from this call-chain:
-cpu_bringup_and_idle:
- \- cpu_bringup
- | \-[preempt_disable]
- |
- |- cpu_idle
- \- play_dead [assuming the user offlined the VCPU]
- | \
- | +- (xen_play_dead)
- | \- HYPERVISOR_VCPU_off [so VCPU is dead, once user
- | | onlines it starts from here]
- | \- cpu_bringup [preempt_disable]
- |
- +- preempt_enable_no_reschedule()
- +- schedule()
- \- preempt_enable()
-
-So we have two preempt_disble() and one preempt_enable(). Calling
-preempt_enable() after the cpu_bringup() in the xen_play_dead
-fixes the imbalance.

-Date: Wed, 1 Feb 2012 16:16:40 -0500
-
-When the initial domain starts, it prints (depending on the
-amount of CPUs) a slew of
-XENBUS: Unable to read cpu state
-XENBUS: Unable to read cpu state
-XENBUS: Unable to read cpu state
-XENBUS: Unable to read cpu state
-
-which provide no useful information - as the error is a valid
-issue - but not on the initial domain. The reason is that the
-XenStore is not accessible at that time (it is after all the
-first guest) so the CPU hotplug watch cannot parse "availability/cpu"
-attribute.
