Public bug reported:
For a while (even with previous ubuntu versions as well), speed of disk
I/O is unacceptable. I thought it is a problem with my machine, but I
have a quite different machine with the same problem now, and also it
was quite OK a year (or years?) ago. Even installing a single deb
package with dpkg lasts for minutes, other processes trying to access of
disk are totally "dead", a single ls command in a terminal can wait for
a minute sometimes. Also, sometimes the mouse cursor can't be moved for
long seconds. There is nothing suspect in kernel log which can help.
During disk I/O top reports wait state for almost all CPU time. Can it
be caused by the pata->libata change for example, NCQ or something like
this? I have no idea how to improve the situation. I can provide
information of course if I know what I should send. Currently these are
machines running up-to-date Ubuntu hardy (32 bit). I can say system is
totally unusable even with smaller disk I/O load ... Thanks in advance!
