Kernel panic after upgrading slackware64-current to 2.6.32.x kernel

Lenard Spencer · 01-20-2010, 11:48 AM

I have one machine where I have several versions installed on different partitions. The base partition (/dev/hda1) is Slack 12.1. On a spare partition (/dev/hdc4) I had installed Slackware64-current. Last week I slackpkg upgraded and installed the 2.6.32.2 kernel, and now that partition will not boot. I know that with the new kernels the hd* designation has been removed, and have already redone that fstab (accessing it from a different boot) to reflect the sd*. Here is the slack64 section of my lilo.conf:

Code:

# Linux bootable partition config begins
image = /other/spare4/boot/vmlinuz
  root = /dev/hdc4
  label = Slackware64
  read-only  # Partitions should be mounted read-only for checking
# Linux bootable partition config ends

I have already tried changing to "root = /dev/sdc4" but lilo errors out trying to install. I cannot upgrade this machine to SATA because it is an older mobo with SATA 1 ports, and will not recognize SATA 2.

What do I need to add to be able to boot this partition? Thanks.

Were you using the default included kernel before? The upgrade kernels given most often need an initrd if you don't want to compile (for me it was ext3 support... had a heck of a time figuring that one out.) it yourself (which I recommend, by the way. just look it up in the slackbook is what I did. It's not as hard as you think. Just remember the framebuffer driver <grin>).

I don't know why the upgrades kernels differ from the prepackaged ones, but they do. They're much more generic.

Although... I hope someone else chimes in because I don't have any experience with -current. This was all on 12.2

If you need to fix up your Slackware after the kernel update where hda became sda then http://alien.slackbook.org/blog/robb...tchover-howto/ may be a useful piece of reading for you.

The same issue one guy posted on Polish slackware forum. He resolved it by:
On slack 12.2:

Code:

# mknod /dev/sda b 8 0 
# mknod /dev/sda1 b 8 1

and then:

Code:

image = /dev/sda1

Or on slackware-current:

Code:

# mknod /dev/hda b 3 0 
# mknod /dev/hda2 b 3 2

an then

Code:

image = /dev/hda2

And refresh lilo.

edit /etc/fstab change hda entries to sda
