Description of problem:
I have written a boot/root creation script for both kernel 2.4.9 and 2.2.19. I
created the 2.2.19 set because there is a bug in 2.4.9 which prevents the root
ramdisk from being loaded on one particular machine I have. At the "VFS:
Insert root floppy disk to be loaded into RAM disk and press ENTER" pressing
enter gives "VFS: Insert root floppy and press ENTER". Since I don't have an
uncompressed root I subsequently get an error message that kernel can't load the
Because this happens only on one machine and only with kernel 2.4.9 I suspect
that it is a chipset dependant problem in the 2.4 kernels.
2.2.19 succeeds with the boot and reports that FDC0 is a National Semiconductor
If there is a way I can get more messages from the kernel to help you out I'd be
happy to do it (floppy=debug made no difference).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
NOTE: This bug only occurs on one of the four systems I have tried it on so
there must be a combination of kernel (since 2.2.19 works) and hardware that
produces the bug
2.Create custom kernel without modules but with floppy
3.Create boot disk
4.Create root disk
5.Reboot system with boot floppy in drive
Actual Results: At the "VFS: Insert root floppy disk to be loaded into RAM
disk and press ENTER" pressing enter gives "VFS: Insert root floppy and press
ENTER". Since I don't have an uncompressed root I subsequently get an error
message that kernel can't load the root partition.
Expected Results: Root disk should have been loaded into ramdisk and system
should boot using root disk.

Scripts, kernel, kernel config, and stripped libc to create boot/root set
7.2 is using 2.4.18 nowadays....
2.4.18 works. This bug can be closed.
