process priority at 25
Hi,
I alway thought process priorities range from -20 to 19 (also according to "man nice"). But under kernel 2.5.16 I run top and process is display with priority 25..
Is there perhaps something wrong?
Thank you,
Axel

First thing i would do is try a "proven" kernel, 2.5.x i belive is development but there again considering the 2.5 kernel series of development is at kernel 2.5.11 i presume you mean 2.4.16.?
At the minute i dont have access to a machine running a 2.4 kernel so i cannot comment further.

It really is 2.5.16 and that is where 2.5 kernel development is at right now.

How correct you are, it seems ftp.nl.kernel.org was behind, i see its been updated now.
I dont follow 2.5 myself.

Kernel 2.4.18 won't run on my off-the-shelf athlon-asus motherboard configuration. Mounting of disks during startup leads to seg faults. 2.4.4 runs with small amounts of seg. faults, caused by an installation of amanda, some month ago. I thought that the uneven numbers are experimental, but the even numbers would be "stable"?

Well it should run ok or at least i have not heard of problems with disk's. Considering you say other kernels give simalar problems then i would say its a local problem and not a kernel issue.
No even or uneven make no differance.
2.5.x are development.
2.4.xx are considered stable.

For example in kernel version number 2.4.18
2 is the VERSION
4 is the PATCHLEVEL and
18 is the SUBLEVEL.
I believe since kernel version 2, kernel development was arranged in a way that even PATCHLEVELs are regarded as a "stable" branch and an uneven PATCHLEVEL is a "development" branch that regular linux users should not work with. It is only for kernel developers for working out a "better kernel". So 2.5 is not for regular use.

Axel

A process's nice value is not the same thing as its priority. niceness is used in the calculation of priority, but they're not bound together. In particular, a process's priority is liable to become numerically greater (-> lower priority) if it makes heavy use of the processor (this is supposed to stop something like ``while (1) ; '' bringing down the system), while a process which makes heavy use of the disk is likely to get slightly higher priority (because as soon as it hits the disk, it blocks, and something else can run).
Under 2.4 kernels, priority is constrained between 0 and 20 (for non-realtime processes), but there's no reason why the same thing should apply to 2.5 kernels.
