new compiled kernel panics. (2.6)

I updated my slack (or tried to) kernel from 2.4 to 2.6

my problem is that when I boot with it I get

Code:

---

VFS: Cannot open root device "342" or unkown-block(3,66)
please append a correct "root=" boot option
Not Syncing: VFS: unable to mound root fs on unknown block (3,66)

---

someone else on the forum had this because of a bad hard drive, I doubt
this is the case though because im running on my old kernel right now (I
was smart and made backups heh)

heres my lilo.conf

Code:

---

# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
boot = /dev/hda
message = /boot/boot_message.txt
prompt
timeout = 1200

im using reifs journeling file system. the kernel is compiled to be native with ext2, ext3, and reifst or however you spell it..

I also noticed that before i get panic alsa dosnt notice my soundcard either.

if you want i can post the .config i used to build it. thanks.

well good and bad news..

turned out during the install for some reason it installed with the ReiserFS with a superblock..

im not sure why, but I compiled the kernel for it, and everything was peachy.

however once it did start up the screen would be out of whack, way to low of a resolution. and it would be unable to find any modules (/lib/modules/) did not have a 2.6 folder just a 2.4

to fix this, I dont really need any modules and im only on this computer for another few months then im upgrading to a while new setup in a whole new place.

so, the resolution issue aside (also did not recognize my eth0) i had a problem which results directly from my stupidity

my lilo.conf had my old linux set to vmlinuz.old

bad, considering that every install I would cp to vmlinuz and it would rewrite it with the previous one.

after 2 attempts at compiling a new kernel that failed (previous kernel panic and blank screen) im left with an unbootable machine

if tried using the slackware linux cd and using /sbin/lilo through it, and although I can specify the map file and the config file it is still unable to find map~ which is some kind of directory or something? which dosnt exist in /boot (on the working partition) and which i cannot copy to /boot on the live-cd

so wtf should I do.. iv tried just running the installer again without formatting and only installing the kernel.. didnt work the installer wouldnt go through. and I cant seem to get to just lilo to set it back up to go to.. not only that, not even sure that vmlinuz-ide-2.4 will work.. should, im hoping it will.

so.. suggestions?

well funny situation, after making the kernel i used make install.. apparently this changed my lilo.conf to use something like root = /dev/fd1

why?? well im not sure.. either way, i mounted my partition. then used lilo -r <mounted dir> and it worked fine.

so im back on 2.4.. fixed the VFS sync problem (or know why it happens now).. my soundcard didnt work because on that version i hadnt enabled hotplugs.

still any reason to the module (dosnt really matter) problem or why my console is so freaking big. ill be working on this but at least I can boot again. (turns out I did have a saved 2.4.31 kernel)

thanks for the help eh? :)
