Compiling kernel 2.4.20 on m68k (success) + X startup problem
Hello,
I was successful in compling the kernel and the modules from the source
package kernel-source-2.4.20_2.4.20-13_all.deb as downloaded from
ftp.debian.org.
Question #1: When compiling the kernel modules, where do they get
placed? Where do I look under /usr/src/kernel-source-2.4.20 to find
them?
I have also downloaded kernel-image-2.4.20-amiga_2.4.20-5_m68k.deb
for comparison purposes.
I had been previously using a 2.4.20 kernel and modules from the
package:
kernel-image-2.4.20-amiga_2.4.20-0.1_m68k.deb
Question #2: I start X at boot time (this was automatically set up when X was
installed). I have noticed on the kernel I compiled myself, and the -5
kernel image I downloaded for comparison, that xdm will die with a
buserr, but runs just fine on the -0.1 kernel. The dmesg fragment is
below:

Xdm starts fine from the startx command (does not generate the buserr).
Has anyone else observed this behavior?
Thanks,
