I can imagine your problem is that either:
- the LowLatency patches might not yet include lowlatencyfying (;^)
ReiserFS (tried ext2?)
- You don't actually have the LL stuff activated. If you built your
kernel with the option "Control low latency with sysctl.", you'll have
to say something like this as root:
# echo 1 >/proc/sys/kernel/lowlatency
because by default in this case LL would be disabled.
(all unconfirmed, just reading through Andrew Morton's page, CMIIW (*)).
