Well have you tried building the kernel yourself? It might be the
options that they are using in the kernel, since the Ubuntu team builds
the kernel with almost everything on, including debugging and sometimes
experimental features.
You could copy your current conf and then take a look at it.

Hi,
This patchset try to solve one deadlock problem which might be caused
by memory allocation with block I/O during runtime resume and block device
error handling path. Traditionly, the problem is addressed by passing
GFP_NOIO statically to mm, but that is not a effective solution, see
detailed
This patch introduces PF_MEMALLOC_NOIO on process flag('flags' field of
'struct task_struct'), so that the flag can be set by one task
to avoid doing I/O inside memory allocation in the task's context.
The patch trys to solve one deadlock problem caused by block device,
and the problem may happen
The patch introduces the flag of memalloc_noio_resume in
'struct dev_pm_info' to help PM core to teach mm not allocating
memory with GFP_KERNEL flag for avoiding probable deadlock
problem.
As explained in the comment, any GFP_KERNEL allocation inside
runtime_resume on any one of device in the
This patch applyes the introduced pm_runtime_set_memalloc_noio on
block device so that PM core will teach mm to not allocate memory with
GFP_IOFS when calling the runtime_resume callback for block devices.

Deadlock might be caused by allocating memory with GFP_KERNEL in
runtime_resume callback of network devices in iSCSI situation, so
mark network devices and its ancestor as 'memalloc_noio_resume'
with the introduced pm_runtime_set_memalloc_noio().

This patch applies the introduced memalloc_noio_save() and
memalloc_noio_restore() to force memory allocation with no I/O
during runtime_resume callback on device which is marked as
memalloc_noio_resume.

If one storage interface or usb network interface(iSCSI case)
exists in current configuration, memory allocation with
GFP_KERNEL during usb_device_reset() might trigger I/O transfer
on the storage interface itself and cause deadlock because
the 'us->dev_mutex' is held in .pre_reset() and the

Hiya, I compiled the kernel with V=1 and noticed "-mno-sse -mno-mmx
-mno-sse2 -mno-3dnow -mno-avx". Is there a way to turn this on? Alt, in
what file is this string, so I can try without it.
Peace Be With You.
