Description of problem:
mkbootdsk formats the floppy to 1430kB
With recent smp kernels the vmlinuz file is too large, leaving insufficient
space for initrd.img
For example running mkbootdisk 2.4.18-24.8.0smp
produces a vmlinuz file of 1159kB leaving insufficient space for initrd.img
which is cut at 264.0kB and can't be gunzipped.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Run mkbootdsk 2.4.18-24.8.0smp (idem with other recent smp kernels)

Actual Results:  The machine cannot be booted from the disk produced.

Expected Results:  It should have booted.

Additional info:

Device full messages are produced when running mkbootdisk
The problem does not occur with the single processor kernel which produces a
vmlinuz file of 1085kB and leaves 73kB free on the floppy.

Comment 1 Peter Vrabec 2004-11-09 14:45:03 UTC
Use another device(cdrom) or floppy with bigger capacity,
also u can compile your own smaller kernel for this purpose.
