Hello,
My D610 ALPS Glide Point is unresponsive with 2.6.21-mm1 patch.
No problem noticed with 2.6.21.
The culprit seems to be git-input. I have applied 2.6.21-mm1 on top of 2.6.21
and then removed git-input patch. It is ok since then.

Currently, devt_attr for the "dev" file is freed immediately on device
removal, but if the "dev" sysfs file is open when a device is removed,
sysfs will access its attribute structure for further access including
close resulting in jumping to garbled address. Fix it by postponing
freeing devt_attr

But the only MMC capable PXA hardware in working conditions I have
access to at the moment is PXA255 based which doesn't suffer from this

The idea in the change was to be able to override NLM_PROGRAM with

We understand that if all mounts are with 'nolock' this wouldn't happen,
and indeed, we configured our mounts t
