ok, but now I have the following problem (I use the jdk 1.3.0 from
blackdown and woody with kernel 2.2.18pre21):

SIGSEGV   11*  segmentation violation
    si_signo [11]: SIGSEGV   11*  segmentation violation
    si_errno [0]: Erfolg
    si_code [0]: SI_USER [pid: 0, uid: 0]

How can I solve this problem? I don't want to use
kernel 2.4.x because I get some problems with my cdrom and my network
adapter (on a powerbook g3 pismo).
