Helo,
Does anybody know why inetd breaks down the kernel?
Kernel 2.2.14 with international patch (but it didn't change select.c,
in which oops happen),
compiled by gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release),
sample ksymoops output following:
Apr 19 15:56:17 p2 kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000000
