kernel 2.6.8.1 & HPT370 RAID 1 array

Hi to everybody,

I have some questions and maybe somebody here on the list can solve my
problem. I'm not subscribed to the list so please e-mail me.
I have been using Slackware 10 with the ataraid.i kernel and it works ok. Now I would like to upgrade to the slackware kernel 2.6.8.1 provided in the /testing directory , which has compilled in some support for hpt370 , but I cant boot with it.
I have two disks in RAID1 and here is my lilo.conf and fstab

# LILO configuration file

# generated by 'liloconfig'
#
# Start LILO global section
lba32 # Allow booting past 1024th cylinder with a recent BIOS
boot = /dev/ataraid/d0
#boot = /dev/hde
#compact # faster, but won't work on all systems.
prompt
timeout = 50
# VESA framebuffer console @ 1024x768x256
#vga = 773
# Normal VGA console
# vga = normal
# VESA framebuffer console @ 1024x768x64k
# vga=791
# VESA framebuffer console @ 1024x768x32k

# ramdisk = 0 # paranoia setting
# End LILO global section
# Linux bootable partition config begins
delay = 50
default = linux-26
image = /boot/vmlinuz
root = /dev/ataraid/d0p3
label = linux
read-only # Non-UMSDOS filesystems should be mounted read-only for
checking
#
image = /boot/vmlinuz-generic-2.6.8.1
root = /dev/ataraid/d0p3
label = linux-26
initrd = /boot/initrd-2.6.8.1.gz
read-only
# Linux bootable partition config ends

And fstab:

root@server:~# cat /etc/fstab
/dev/ataraid/d0p1 swap             swap        defaults         0   0
/dev/ataraid/d0p3 /                reiserfs    defaults         1   1
/dev/ataraid/d0p2 /boot            reiserfs    defaults         1   2
/dev/ataraid/d0p4 /home            reiserfs    defaults         1   2
/dev/cdrom       /mnt/cdrom       iso9660     noauto,owner,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
none            /sys            sysfs           defaults        0   0

So when I boot from the 2.6.8.1 kernel, it stops with kernel panic
VFS: Unable to mount root fs on unknown-block(114,3)

If somebody can enlighten me I would really apreciate it.

Thanks for your time and best regards.

I'm not certain but your problem could very well be that the device names for SATA devices are different under 2.4.x kernels making your fstab invalid.

My understanding is 2.4 uses different code for SATA support than 2.6 does and they assign different device names. 2.6 uses libata and 2.4 uses ... ? The matter is futher complicated by the fact that libata has been recently backported to 2.4.27.

I have recently been trying to get some clarity on this issue myself so hopefully others on this list can shed some light on it.

This is exactly what I was thinking when I check the fstab. But who knows. I have tried to find some docs in the kernel source for RAID but have not been succesfull.

Yes I hope somebody can help me with that.
