swapon -a does not work when bootin, but it _does_ work from the command line


I'm having a problem with getting swap to work on my debian sarge stable 

I'm havig two hard disk, one normal IDE-drive an one SATA. GRUB is avtivated 
from the SATA disk, but the version I'm having problem with (2.6.8-2-k7) is 
on the IDE, drive (on the SATA drive I'm experimenting with AMD64/-k8 
kernel). The swap space in on the SATA Disk.

My problem is that my swap space does get activeted at boot time. My fstab 
looks as follows:

# /etc/fstab: static file system information.
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/hda1       /               ext3    defaults,errors=remount-ro 0       1
# Jan: Added swap
/dev/sda5       none            swap    sw              0       0
/dev/hdc        /media/cdrom0   iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0

If I login I'm abel to activate the swap space with the following command (as 
# swapon -a

This command is also present in the appropriate ini/rc scripts

# grep -r swapon /etc/*
init.d/checkroot.sh:    swapon -a 2> /dev/null
init.d/mountall.sh:# Execute swapon command again, in case we want to swap to
init.d/mountall.sh:     swapon -a 2> /dev/null
rcS.d/S10checkroot.sh:  swapon -a 2> /dev/null
rcS.d/S35mountall.sh:# Execute swapon command again, in case we want to swap 
rcS.d/S35mountall.sh:   swapon -a 2> /dev/null

Which is exactly the same as on my SATA partition with the 64-bit linux kernel

I suspect that somehow the SATA disk is not avaliable at that tiem in the boot 
process - but unfortuantely I have no clue about how to remedy the problem: I 
tried to mount  the SATA partition by adding the following line in /etc/fstab 
(before the lines whith the swap partiiton)

/dev/sda1       /mnt            ext3    defaults,errors=remount-ro 0       2

- but this only resutled in that the boot process stopped and claimed that the 
partioin was not an ext2 filesystem

As you might suspect it is no problem to mount sda1 once I have logged in:

#mount /dev/sda1 /mnt

As I wrote above I suspect that at the time that mounting/swap activation 
occurs the system has no support for SATA drives - unfortunately I do not 
know which steps to take to remedy the problem (ensure drivers are loaded, 
etc), so any help would be higly appreciated.

Best Regards - Jan

P.S. I'm aware of that I could probably solve my problems by creating a swap 
file on /dev/hdc, but that would not really solve the boot/mount problem 
although swap activation would be automated
