Hi,
I am new to ELKS.
I am using elks-0.1.1,elksnet-0.1.1,
elkscmd_20020501.tar.gz,Dev86src-0.16.11.tar.gz
I am compiling on a Pentium - Linux Kernel 2.4
I have been able to compile and get all the Binaries.
The boot floppy comes up fine.
The root floppy is giving me a panic
***********************
ELKS version 0.1.1
fd: probing disc in /dev/fd1
fd: /dev/fd1 probably has 18 sectors and 80 cylinders
VFS: Mounted root (minix filesystem).
Loading init
sys_execve("/bin/init",args,18) => 65528.
panic: Oops - trying to access dir
apparant call stack:
(0) ret addr = 3296 params = 67B4 26C4 2 26D0 2F64 0
(1) ret addr = 33F4 params = 3D6 26EA 26EC 67B4 26E6 80
(2) ret addr = 35C3 params = 3D6 3 8000 2706 0 3
(3) ret addr = 41C0 params = 3D6 2 0 310 FFF8 2268
(4) ret addr = 103 params = 0 0 0 0 0 0
(5) ret addr = 0 params = 2268 A9 9FC0 2C74 3FF2 1E
(6) ret addr = 9C params = E120 1DA4 E5EC 0 0 1
*********************
I saw an identical posting by Mark Robson in Mar 03. I did not find a
solution to it.
It looks like the init is not able to get executed.
Has any body faced this problem ?
Please help.
Bye,
raghavan V

That 65528 is -6 written as an unsigned integer, and indicates a bug
in the printk routine (more specifically in the numout() routine it
calls to actually display the values). I have just committed a patch
to fix that bug, and the patch is enclosed.

We really need something to convert those return addresses into actual
routine names, as the addresses themselves are basically meaningless 8(

Unfortunately, I can't help with your problem itself. Sorry.
Best wishes from Riley.
