Could you rewrite it so it says what you mean to say. You ask the recipient to be careful --- okay. You talk about a real-time kernel and an older kernel. Then you say, "However,,, " What do you mean ScottL. Say it without all the extras! Kenneth </blockquote><div> Kenneth, Certainly. While the individual facts are simplistic, the aggregate can be complicated. Therefore I'll use short sentences to step through the logic. The OP stated that he had installed Ubuntu Lucid (10.04) but wanted to upgrade to Ubuntu Studio. Ubuntu and Ubuntu Studio include the 2.6.35 kernel in a default installation in lucid (10.04). A real-time 2.6.35 kernel is not available in any of the official repositories in Ubuntu. The linked documentation to upgrade to Ubuntu Studio suggests installing the linux-rt package. The linux-rt pacakge for lucid (10.04) is a 2.6.31kernel with real-time preemption. Note that this is an older kernel version. Therefore, if Aradnix complied absolutely with the documentation's suggestions he would experience a regression in kernel version. Real-time preemption would be gained but the older kernel version (2.6.31) may not include some particular hardware driver that was included in the default installed kernel (2.6.35) included with Lucid. This may or may not be a problem depending on his hardware. I apologize if this seemed pedantic but I want to make sure that everyone understands. Please let me know if I can help further. ScottL P.S. My understanding is that the reason for the discrepancy between generic and real-time kernel versions is because a patch (historically from Ingo Molnar) is required to create a real-time kernel and the patch is not made for every available kernel. </div></div>
