Thip patchset avoids accessing auto-suspended device in ioctl path,
which is generally triggered by some network utility(ethtool, ifconfig,
...)
Most of network devices have the problem, but as discussed in the
thread:

the problem should be
This patch introduces the below two helpers to prepare for solving
the usbnet runtime PM problem, which may cause some network utilities
(ifconfig, ethtool,...) touch a suspended device.
usbnet_read_cmd_nopm()
usbnet_write_cmd_nopm()
The above two helpers should be called by
This patch applies the introduced usbnet_read_cmd_nopm() and
usbnet_write_cmd_nopm() in the callback of resume and suspend
to avoid deadlock if USB runtime PM is considered into
usbnet_read_cmd() and usbnet_write_cmd().

This patch fixes memory leak in smsc95xx_suspend.
Also, it isn't necessary to bother mm to allocate 8bytes/16byte,
and we can use stack variable safely.

This patche gets the runtime PM reference count before calling
usbnet_read[write]_cmd, and puts it after completion of the
usbnet_read[write]_cmd, so that the usb control message can always
be sent to one active device in the non-PM context.

Sorry, I just rebased that on 3.7.0-rc3-next-20121102.

Well,
The issue appeared again.
irq 18 was disabled, one pwc webcam was on that irq.
This time on new hardware: Gigabyte F2A85X-UP4 with A10-5800K APU.
The box was busy with it's raid10 array, this time, by running bonnie++;
also a raid-check was in progress. (unknown at the time)
So what does

I've a strange problem with the USB subsystem, under

[PATCH 3] Rename link file's name child to device, add check of

Change since v2:
[PATCH 1] fix a logic backward problem. Add changelog about change ehci
root hub descriptors based on ACPI
This patch is to set xhci root hub's DeviceRemovable according to usb port's
connect type which currently comes from ACPI information rather than xhci PORTSC
register due to Windows prefers to ACPI information. If ACPI information was
different with PORTSC, there would be a warning.
Some platforms provide usb port connect types through ACPI. This
patch is to add this new attribute to expose these information
to user space.

It looks like these patches were not a good idea, because in each case the
printk provides an error level, and WARN then provides another one.
Sorry for the noise.
