Thanks. Indeed, the same upgrade pulled in the 2.4.27-1-686 update.
Would you like me to attempt installing an earlier 2.4 version to check if it
is indeed the case? which one?

I have just spent a couple of hours trying to do it in a way that would allow
me to select between the 2 kernels, and the results are as follows.
1) Just attempting to install it out of the box and booting resulted in a
panic. Here are the messages it says before the panic:
pivot_root: no such file or directory
/sbin/init: 426: cannot open dev/console: no such file
Kernel panic: Attempted to kill init!
2) the reason turns out that my IDE drive is a SATA controller
0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150 Storage
Controller (rev 02)
which is treated differently by 2.6 as opposed to 2.4, so that the drive
becomes sda as opposed hda. This requires manual setting of the kernel
options in /etc/grub/menu.lst to select the appropriate root device,
but I have not figured a clean way what to do with /etc/fstab !
Here's what I have there at 2.4:
/dev/hda1 / ext3 defaults,errors=remount-ro 0 1
/dev/hda4 /LOCAL ext3 defaults 0 2
/dev/hda5 /boot ext3 defaults 0 2
/dev/hda9 /home ext3 defaults 0 2
/dev/hda8 /tmp ext3 defaults 0 2
/dev/hda6 /usr ext3 defaults 0 2
/dev/hda7 /var ext3 defaults 0 2
/dev/hda2 none swap sw 0 0
/dev/fd0 /floppy auto
rw,user,noauto,umask=077,shortname=winnt,showexec=no 0 0
/dev/cdrom /cdrom auto ro,user,noauto 0 0
proc /proc proc defaults 0 0
/dev/sda1 /memory_card vfat
rw,user,noauto,umask=077,shortname=winnt,showexec=no 0 0
/dev/sda2 /keycard ext2 rw,user,noauto,nosuid 0 0
/dev/sdb1 /olymp vfat
rw,user,noauto,noexec,umask=022,shortname=winnt,showexec=no 0 0
3) When I solve that, I will have to solve another issue which is the CD-R.
Currently, under 2.4, I am using scsi emulation for both the IDE CD-ROM and
the CD-RW device:
/proc/cmdline: ... hdc=ide-scsi hdd=ide-scsi
and in /etc/modules:
sg
ide-scsi
Also I have the corresponding links established from /dev/cdrom and /dev/cdrw
As far as I understand, I have to remove all this under 2.6, so there's quite
a bit of work left.
Any link on setting up the 2 kernels in parallel on the same machines are
appreciated (this is a family desktop machine and I am unsure I am willing to
make the wife and the kids suffer a kernel I haven't tried out here myself
yet).
Kind regards,
v.
