I'm sorry. I'm not familar with those applications to get any useful information out of them. Any quick information on what i should be doing with it would be appreciated. > Hmm, I'm pondering what I'd do here... > Could it be that you're using the "old" IDE layer (not libata yet) and > hdparm -u or -d or -c is inconveniently set up? > Try configuring a different CONFIG_HZ? > And did you try running a "barebone"-only configuration? Possibly some > certain driver is causing this misbehaviour... I'm already keeping the config as clean and minimal as i can imagine. Anyway... I recompiled the kernel (2.6.22.2 now) with pure libata, CONFIG_HZ to 1000 (instead of 250). No effect yet. > Or maybe it's a simple X.org scheduling issue again? > What nice value do you run X.org at? I'm using the default niceness which should be 10 no?

Well the system is low on memory (312M) but that was the last thing i would've been looking for since it somehow got the win32 gui and some games to render and work properly on it. > Maybe run powertop to identify timer anomalies? This shows two interesting lines: 56.5% ( 21.6) : extra timer interrupt 11.0% ( 4.2) : libata > Oh, given that IIRC the Webboy is a slightly older Gericom model which > thus may easily be a (somewhat hotter) P4 *desktop* CPU It's a pentium-3. model name : Pentium III (Coppermine) stepping : 10 cpu MHz : 1097.269 > could it be that > you're hitting thermal emergency throttling on increased system activity? > cat /proc/acpi/processor/*/throttling or something there might indicate > this. When am I supposed to check this? During idle it's like the following: state count: 8 active state: T0 states: *T0: 00% T1: 12% T2: 25% T3: 37% T4: 50% T5: 62% T6: 75% T7: 87% Any additional comments on this? :) Thanks a lot. -- MfG Mierswa, Daniel
