New kernel causes kernel panic

[Marc Dubrowski <marcus@axp02.kbinirsnb.be>]

Hello everybody,

I'm a newbie in compiling kernel, and I don't know exactly what problems are
caused by 2.2.x kernels

I've tried compiling one, and the make menuconfig, make dep make clean and make
ran just fine. It was the kernel provided with slink's packages: kernel-2.2.1.
I don'yt know if it's normal or not, but the make zImage or make vmlinuz didn't
work, so I just typed 'make', and I got a brand new vmlinux file.

I Gzipped it to have it vmlinux.gz, and put the file in the root directory ( /
), beside the vmlinuz file of the kernel 2.0.36.

I work on an alphastation 200 4/166.

I still use the milo version from the debian slink distribution, and the root
directory is on the sda7 partition, so the option in Arcbios for booting are:

boot sda7:vmlinuz root=/dev/sda7

after having replaces vmlinuz with vmlinux.gz, and rebooting, the system seems
to reboot correctly after it finds 3 network devices (eth0, eth1 and eth2; butI
only have two):

eth0: Digital DC21040 Tulip at 0x8800,08 00 2b e6 7a 97, IRQ 15
eth1: Digital DS21142/3 Tulip at 0x9000, 00 00 f8 1a b5 57, IRQ 14.
eth1: Index #0 - media 10baseT(#0) described by a 21142 serial PHY (2) block
eth1: Index #0 - media 10baseT-FD(#4) described by a 21142 serial PHY (2) block
eth1: Index #0 - media 100baseTx (#3) described by a 21143 SYM PHY (4) block
eth1: Index #0 - media 10baseTx-FD(#5) described by a 21143 SYM PHY (4) block
eth2: region already allocated at 0x8800.
eth2: region already allocated at 0x9000.


and then says:

VFS: cannot open root device 08:07
Kernel panic: VFS: Unable to mount root fs on 08:07

And then, everything is stopped, and I have to reboot.

Could someone explain what the problem can be, or direct me to some information.


Thanks
