Hi, and thanks for the reply.
The reason for using an outdated SDK is simply that we already have a
lot of products sold and in use. We are obligated to offer maintenance
to our customers, so at the moment it is hardly possible to upgrade the SDK.
BTW, problem is actually solved; some little patching to the
kernel_menuconfig did the trick :)
It would be interesting to know what that "trick" was.
The open implementation in all char drivers in Linux hold the
"big kernel lock" (BKL ?). So putting an infinite loop in
there is going to cause havoc. The watchdog, or something it
triggers, may well get stuck waiting for the BKL to clear.
