I tried to understand if with 2.5* my hd is too slow, but hdparm -t -T gives me better results then 2.4.19. I _can not_ reproduce this issue with 2.4.19 Following a part of the top -b > foo output, if you need I can post the entire output. Is it a known issue ? And, is it a problem or am I just trying to run the kernel with too few memory? If you want to replay this email please cc me ;-) Ciao, Paolo 21:59:09 up 6 min, 3 users, load average: 0.91, 0.57, 0.28 34 processes: 33 sleeping, 1 running, 0 zombie, 0 stopped CPU states: 24.9%
