I'll try to do so. My main concern is that even if it has been corrected
in the last kernel, I'm not free to just use the last kernel; our customers
already have units in their hands, and they bought us a "Form Fit & Function"
plattform. We have a huge bunch of documentation coming with each deliverable
(part of an ISO process, following IEEE software standards). So for the
company, migrating to the latest kernel is the last resort because of the
amount of work it would require. Thanks for the idea, I'll let you know.
