SubjectRe: System freeze on 2.4.18 / 19 SMP
Date

yes alsa is running too - i'll deactivate it next time.

It just tried to run the installer on a PII 400MHz with SuSE kernel 2.4.18-4GB
and only 128MB of physical RAM / 380 MB swap (short test, i will recompile
the 2.4.19 later):

- the installer itself (java-app) crashed with segmentation fault
- afterwards the system is unstable, starting the installer again leads to
kernel messages as follows and even "umount" gets a segmentation fault.
