Sorry for the harsh critics. There have been some quality issues with openSUSE
11.2 which I have not addressed in time (although this is not the right place
to complain.).
The problem is not openSUSE specific as it occurs on Debian, Ubuntu,
RedHat/Fedora and Mandriva as well. Nonetheless it would be really great if you
could do anything about it!!
Kernel downgrading does not seem to be an option since kernel 2.6.25 (no
ksoftirqd problem) seems to inhibit some powersave scripts with a root cause at
me. Isn`t it simply possible to diff all changes from kernel 2.6.25 to 2.6.27?
This is a lot of work sure, but it needs to be done as the problem has not been
resolved by time. The ksoftirqd-hangs may often be bearable on a dual core
machine though it sometimes causes that massive disk access that a hard reset
is the only escape. Perhaps kernel developers of other distros could help us.
It should be possible by a conjoint effort.
