Subj: linux kernel 1.3.83 boot problem more Info.

Hello,
Somebody please help me. Below is information about my system and the
problem I had installing linux kernel 1.3.83.

1. System Info.

1.1 CPU : 486DX2
1.2 Memory : 32MB
1.3 Linux Version : 1.3.9
1.4 Gcc Version : 2.7.2
1.5 IDE Disk : Western Digital Caviar 2100 1.0GB
1.6 Disk Controller : Adaptec AVA2825VL SCSI and IDE Controller.

2. Linux kernel 1.3.83 boot problem

2.1 System is able to boot successfully with kernel 1.3.9 with Hardware
mention in Item 1.

2.2 Compiled the new kernel 1.3.83 without any errors. Make config was
selected for every thing as module except ext2 file system and IDE
controller. Installed the new kernel using lilo. Started boot with
1.3.83 all the hardware is detected boot kept going upto point where
the console displayed the line given below and it hangs up.

VFS: Mounted root (ext2 filesystem) readonly.

Booted from rescue floppy and installed the kernel 1.3.9 back and
booted with success.

2.3 Compiled the new kernel 1.3.83 without any errors. Make config was
selected for minimum kernel no modules. Installed the new kernel using
lilo. Started boot with 1.3.83 all the hardware is detected boot kept
going upto point where the console displayed the line given below and
it hangs up.

VFS: Mounted root (ext2 filesystem) readonly.

Booted from rescue flopyy and installed the kernel 1.3.9 back and
booted with success.

2.4 Did some investigation by placing some printk lines in the init/main.c
and found out that the kernel goes into a infinite loop in the function
static int init(void * unused) in the code given below:

while (1) {
pid = kernel_thread(do_shell,
execute_command ? execute_command : "/bin/sh",
SIGCHLD);
if (pid < 0) {
printf("Fork failed in init\n\r");
continue;
}
while (1)
if (pid == wait(&i))
break;
printf("\n\rchild %d died with code %04x\n\r",pid,i);
sync();
}

2.5 At this point I do not know how to proceed with more testing.

3. Please let me know if this is known or unknown bug and if there is fix for
this problem.

Regards,
Ramneek
