If a DVD is in the drive, the same message will be repeated over and over several times per second. The system is an openSUSE 10.3 with the modifed kernel, KDE3 and all the fancy auto-mounting stuff. The kernel is not compiled for SMP (that gave other errors which were already discussed on LKML). Hardware is a Pentium M processor on an industrial PC board with Intel chipset and integrated graphics. Any ideas how to fix this? If you need any more information or if I can test something, please let me know. Bye, Jürgen
