[SOLVED] boot into Slackware

nova49 · 02-11-2011, 04:05 PM

I was recompiling my kernel to fix another problem I had. I was following alienBob's tutorial if it means any thing. Any way when I booted it up I got a kernel panic. The error is
Kernel Panic - not syncing: VFS: unable to mount root fs on unknown-block(8,2)
I think its something to do with lilo or I flubbed something up. I am just mentioning this for advice.

My real problem is that I cant boot into the OS to fix it. I tried using the cd but all that tried to do was reinstall it.

Re-read the screen on the install disk. You can use it as a rescue disk by booting the kernel from the disk, but use your actual root partition.

You probably forgot to add your filesystem support or you just need an initrd. See: http://alien.slackbook.org/dokuwiki/...ting_an_initrd

Ok I got it to work. Now I just need to figure out why my mouse and keyboard dont work. Thank you for the help.

Are they usb? Did you include usb support?

nova49 · 02-11-2011, 05:02 PM

I booted from the kernel on the cd. How do you enable usb devices from the default cd kernel?

I tried to use a ps2 keyboard I had laying around and that doesn't work either. Would it be faster to just reinstall the OS and start again?

Reinstalling the whole system would indeed be faster, but is not the fastest. As you retain the ability to go online, you can download the kernel packages (modules, source, image, etc) and install them chrooting. I would still try to fix whatever you may have done so that you won't do the same anymore and still get to learn a lot about Linux.

Have you looked up what drivers where loaded on the running system?
If you start from a live cd you could try

Code:

# lsmod

to see what modules are loaded. This way I found out, that I needed a NVIDIA module for, hmmm, I think it was IDE and SATA support. I don't remember, it was on my old PC.
On my current I was just to lazy to build an own kernel. I just took the original one and activated big memory support so I can use my entire 4 GB of RAM on my 32 bit system.
