Works on a 2.6.27 kernel on a x86_64 machine and possibly others. Backward compatibility seems to be fine with older kernel versions. migrated the old nopage() code into the new fault() method in the virtual memory management system for the DMA buffer.

Aug 09, 2009 issue 3 (nopage issues in usbtimetag driver) reported by christian.kurtsiefer - What steps will reproduce the problem? 1. try to say make in the usbtimetagdriver directory 2. look for a bunch of errors regarding missing 'nopage' methods 3. What is the expected output? What do you see instead? does not comile. Problem is a change in the virtual memory management structures in the kernel sometimes after kernel version 2.6.22; apparently the new fault() mechanism was introduced in 2.6.23 to superseed the nopage() and other methods. For sure, the nopage method has gone in kernel 2.6.27 used in SuSE11.1, but it seems that migration is not too complicated. Migration is in progress and compiles, needs to be tested before the next commit. 10.8.2009chk What steps will reproduce the problem? 1. try to say make in the usbtimetagdriver directory 2. look for a bunch of errors regarding missing 'nopage' methods 3.

Unclear yet. Usually operation over several hours, sometimes under increased system load by other processes on the machine. What is the expected output? Termination of costream with file inconstency message, a trace in the ecd log files of similar flavour. Problem description: At various places in the code, read(2) statements are called without proper handling of return values where less than the file size or requested buffer size are filled into the buffer. This results in a failure of content consistency checks, and a subsequent abort of the normal flow. At some parts in the code, the problem is addressed by reading the length of a file with a stat command, but it seems a bit bulky to implement that for all read attempts. Suggestions welcome.

Operatate key generation for times over 19 hours, more specific information not available 2. 3. What is the expected output? What do you see instead? The extension of the intrinsic timing information together with the local computer time should take care of that problem completely, but it seems to fail sometimes. Reason for that so far is unclear, not even where the system hangs. Please use labels and text to provide additional information. What steps will reproduce the problem? 1.
