Unhappy New Kernel = No Mount?


Hi! i have this problem when ever i build and install a kernel newer that the ubuntu supplied linux-source-2.6.12, i have tried every kernel from rev from 2.6.13 to 2.6.15 with the same result.

I can't mount my storage drive!!! lol

the system recognized that the an EXT3 partition is there but when i try to mount it i get the old "mount: /dev/hdc1 already mounted or /media/storage busy" (/dev/hdc1 is the storage drive on my machine)

I have a media drive in /dev/hdd1 (also EXT3) that loads up just fine.. but not the /dev/hdc1.

this is my "mount" output:

Quote:
/dev/hda6 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
tmpfs on /dev type tmpfs (rw,size=10M,mode=0755)
/dev/hdd1 on /media/multimedia type ext3 (rw,nosuid,noatime,user_xattr)

this is my "mount /media/storage" output

Quote:
mount: /dev/hdc1 already mounted or /media/storage busy

"mount /media/multimedia" works just fine.

if i boot back to my 2.6.12 kernel the drive mounts up just fine... its is odd...

i never had this kinds of problems using straight up debian, but i guess its a kernel patch thing.

I am guessing that some driver or component in your new kernel is not compiled, and is somehow needed to access the drive (even though you specify it was being straight EXT3).

The only think I can think of checking might be that the .ko modules in

/lib/modules/2.6.12/kernel/fs/

match the .ko modules in

/lib/modules/2.6.14.3/kernel/fs/

(at least on my system - obviously if you have a different version of the kernel, use your kernel version number)

If they don't you'll need to reconfigure the new kernel, until they do.

This will of course only be a valid method if the relevant stuff is compiled as modules, and not into the kernel itself.

The only other thing to do might be to run make xconfig on the new kernel, and then in a different terminal examine all relevant config file sections, making sure that your new kernel's config file exactly matches the old kernel's config file in all respects (except for new options in the new kernel, of course).

This may be very time consuming, but using this approach I successfully migrated my FC3 system from 2.6.12 to 2.6.14.3, and I am very happy with the results.

Just curious, what kind of drive is /dev/hdc? Make sure you have support for the method either compiled in or compiled as modules, otherwise, the system cant even recognize the connection. This makes more sense than a filesystem problem, as it's the same type as previously mounted drives.

You'll be missing something in the kernal config. Filesystem, dma chipset, whatever... Check the config carefully, or use the original kernel source config as a start point and make oldconfig on the new kernel.
