It neems that CVS isnot any morel compatible with 2.2.17 kernel ?

Wed Aug 14 02:59:43 EDT 2002

Hello,

I use an ELAN-104NC PC Board.
It use JFFS/MTD with the 2.2.17 kernel.
I actually use an old CVS snap shot (15 September 2000)
It work well but it is quit slow (~ 1min to mount the
JFFS file system)

So wanted to update.
I download the last CVS today.
I download linux-2.2.17 from kernel.org

I patch the kernel with :
- inter-module-2.2.17
- mtd-patch-2.2.17-20001218-2230GMT
build zImage
All goes right

BUT at run time when i boot the kernel it got this :
(my root is 1f:02 it i a JFFS partition)

...
ELAN-104NC flash: IO:0x22-0x23 MEM:0xb0000-0xb7fff
ELAN-104NC flash: Found 1 x16 CFI device at 0x0 in 16 bit mode
...
JFFS version 1.0, (C) 1999, 2000 Axis Communications AB
ll_rw_block: Trying to read nonexistent block-device 1f:02 (1)
EXT2-fs: unable to read superblock
Invalid session number or type of track
ll_rw_block: Trying to read nonexistent block-device 1f:02 (32)
isofs_read_super: bread failed, dev=1f:02, iso_blknum=16, block=32
VFS: Mounted root (jffs filesystem) readonly.
Freeing unused kernel memory: 48k freed
...

I try to BUT

what does mean :
ll_rw_block: Trying to read nonexistent block-device 1f:02 (32)
isofs_read_super: bread failed, dev=1f:02, iso_blknum=16, block=32

Is it dangerous ?

So i tried to put last CVS mtd : i patch with
sh patchin.sh /usr/src/linux

But when i try to compile i got this :

make zImage
...
make -C mtd

make[2]: Leaving directory `/usr/src/linux/drivers/mtd'
make[1]: *** [_subdir_mtd] Error 2
make[1]: Leaving directory `/usr/src/linux/drivers'
make: *** [_dir_drivers] Error 2

I do not undesrtant but i try this
cd /usr/src/linux/include/linux
ln -s ../asm-i386/spinlock.h
cd /usr/src/linux
make zImage

Is it a good idea ?
It seams not because few secand later i stop with that :

Does some one understand what append ?
I am curous to know the truth.
