Good Evening,
Few days ago my machine crashed and i got error noted in subject line. I
was installing Cisco Call Manager on Vmware work station. I googled around
but nothing specific. Please tell me what it means, and if this is one time
issue. Haven't seen it before, and this about twentieth time am doing this
type of installation.
After power cycling everything istalled and i have 4 Call Manager running
on this ubuntu machine.
Attached are additionally screen shots of the incident.
Thanks for all your help.

>
> Haswell LynxPoint and LynxPoint-LP with the recent Intel BIOS show
> mysterious wakeups after shutdown occasionally. After discussing with
> BIOS engineers, they explained that the new BIOS expects that the
> wakeup sources are cleared and set to D3 for all wakeup devices when
> the system is going to sleep or power off, but the current xhci driver
> doesn't do this properly (partly intentionally).
>
> This patch introduces a new quirk, XHCI_SPURIOUS_WAKEUP, for
> fixing the spurious wakeups at S5 by calling xhci_reset() in the xhci
> shutdown ops as done in xhci_stop(), and setting the device to PCI D3
> at shutdown and remove ops.
>
> The PCI D3 call is based on the initial fix patch by Oliver Neukum.
>
> [Note: Sarah changed the quirk name from XHCI_HSW_SPURIOUS_WAKEUP to
> XHCI_SPURIOUS_WAKEUP, since none of the other quirks have system names
> in them. Sarah also fixed a collision with a quirk submitted around the
> same time, by changing the xhci->quirks bit from 17 to 18.]
>
> This patch should be backported to kernels as old as 3.0, that
> contain the commit 1c12443ab8eba71a658fae4572147e56d1f84f66 "xhci: Add

> Subject: dm snapshot: fix data corruption
>
> commit e9c6a182649f4259db704ae15a91ac820e63b0ca upstream.
>
> This patch fixes a particular type of data corruption that has been
> encountered when loading a snapshot's metadata from disk.
>
> When we allocate a new chunk in persistent_prepare, we increment
> ps->next_free and we make sure that it doesn't point to a metadata area
> by further incrementing it if necessary.
>
> When we load metadata from disk on device activation, ps->next_free is
> positioned after the last used data chunk. However, if this last used
> data chunk is followed by a metadata area, ps->next_free is positioned
> erroneously to the metadata area. A newly-allocated chunk is placed at
> the same location as the metadata area, resulting in data or metadata
> corruption.
>
> This patch changes the code so that ps->next_free skips the metadata
> area when metadata are loaded in function read_exceptions.
>
> The patch also moves a piece of code from persistent_prepare_exception
> to a separate function skip_metadata to avoid code duplication.
>
