[parisc-linux] PALO and ramdisk micro-howto

[Paul Bame]

Grab recent versions of these from CVS:
	palo sources
	linux-2.3/init/main.c
	linux-2.3/arch/parisc/kernel/setup.c

In palo/Makefile, comment out NFSROOT= and uncomment the RAMDISK= line
which assumes your ramdisk is the file ../linux-2.3/ramdisk.bin which
is the way we used to have things.  Make sure you have a ramdisk in that
file (or change RAMDISK=).

Next time you 'make palo' in your linux tree, palo inserts the ramdisk
inside lifimage and constructs a default kernel command line to use the
ramdisk.

I tried both the old ramdisk, and I turned willy's nfsroot into a
ramdisk, and both booted and loaded but died with that
'Kernel panic: Attempted to kill init!' message.  Looks like sash is
being started with some args it doesn't like and exiting with a usage
message.

Fixed by new palo/ipl.c

I tried this with my 715/50 and current CVS kernel and palo as of today.

I got the following results:

[...]

RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize
SCSI clock: 50000000
Lasi Scsi (53c700) found at 0xf0825100
scsi-ncr53c7xx : unsupported SCSI chip 700
scsi : 0 hosts.
scsi : detected total.
IP-Config: No network devices available.
RAMDISK: ext2 filesystem found at block 0
RAMDISK: Loading 600 blocks [1 disk] into ram disk... done. 
kernel BUG at block_dev.c:411! 
kernel BUG at block_dev.c:411!


Any ideas?

those two are OK, they should disappear when we go to the latest Linus
tree.  What's happening at this point is that it's switching to serial
console.  You should be able to stay with PDC console for the time being,
though you can't use it as an input device, only output.  In the fullness
of time, we'll have a proper graphics console.  Stay tuned :-)

[parisc-linux] Eth0 trouble

[Thierry SIMONNET]

I have generated new lifimages with differents methods (ramdisk, nfsroot and
disk) using palo.
I have the following messages :
    eth0: receive unit error
    eth0: Null rbd - oops!
     eth0: receive unit error
    eth0: Null rbd - oops!
    eth0: receive unit error
    eth0: Null rbd - oops!
    eth0: receive unit error
    eth0: Null rbd - oops!
....

Before this messages, everything is OK. sash works fine, and I can execute
some test programs. After that, I lost LAN connectivity.

My config is  : 712/80 Workstation, with latest binutils, gcc, linux-2.3 and
palo.

Have an idea?
