Hi Andrew, hi Con, > Here's a diff against base 2.4.20. It may be a little out of date > wrt Andrea's latest but it should tell us if we're looking in the > right place. Ok, I did not run the complete 2.4.20aa1 kernel yet since I am not sure if it is intended to be used, but I applied your patch, Andrew (thanks for mailing it). It still does not fix the problem. One job doing much I/O starts with about 80% CPU but then drops down to about 30% in the first 40 seconds. Load goes from 0.00 to 2.4 within that time. And I can see bdflush and my process marked with "D" in the process list. Catting the device to /dev/null only made it worse :-( Creating a 1GB file using dd takes about 1 minute compared to 16 seconds without other jobs running. Do you think it could be a ReiserFS problem on a RAID? Do you know of anything else I could try? Sorry, but my knowledge doesn't reach that far.
