I'm new in slackware and I did this to add a system call.



>added gb.c in usr/src/linux/kernel
>added gb.o into obj-y =
>added #define __NR_gb 341 in "/usr/src/linux/arch/x86/include/asm/unistd_32.h "
>added asmlinkage int sys_gb(); in "/usr/src/linux/arch/x86/include/asm/syscalls.h"
>added .long sys_gb in "/usr/src/linux/arch/x86/kernel/syscall_table_32.h"
>So that's done

>slackpkg update

#Compiling part#
make xconfig
make
make modules_install install
cd /boot
mkinitrd -o initrd-img-2.6.37.6 2.6.37.6
"edited lilo added initrd= /boot/initrd-img-2.6.37.6"
lilo
init 6 (reboot)

then it gives me the tty error in boot up

Another post where a lot of data on context is missing... What are you talking about? Which system call? For what purpose? Who wrote what? (Did YOU code something or did you get a THIRD PARTY patch ?)...

Edit: Use the 'CODE' tags to write your dumps and code... Also tell us what was the command which dump that stuff...

What is the exact boot error that you get?
And yes, I agree that a little more context would be helpful.
BTW, have you read the README.initrd document?

And the contents of gb.c might be nice, too.

Also, which .config did you use? One of the stock ones in /boot, a zcat /proc/config.gz > /usr/src/linux/.config, or whateve was in the linux source to start with?

sorry, besides clarification questions above, how your kernel hacking relates to Slackware?
