Going from 2.2.12 to 2.2.17pre10

Hi!

I'm trying to go from 2.2.12 to 2.2.17pre10 on an MVME 2400.

A few problems:

The Motorola SROM bug-patch lacks one row in de4x5.c:

        lp->infoblock_csr6 = OMR_MII_100;
        lp->useMII = TRUE;
        lp->infoblock_media = ANS;

This one was easy. Now for the hard one. :)

I'm using a PMC-harddisk based on the CMD-646 chipset (Ramix 233).

I installed my system under 2.2.12 with Debian.

When I come to the partition check in 2.2.17pre10 it fails with
"hda: unknown partition table"

I added a printout in drivers/block/genhd.c in msdos_partition()

        }
        p = (struct partition *) (0x1be + data);

With this I get the following printout:
hda:Data: aa55 LABEL:55aa

So it seems like the byte order is wrong. Does anyone know why this
happens?

Please don't tell me my 2.2.12 partitioned disk is wrong. :)

Where do I go for the best LinuxPPC 2.4 kernel for MVME-boards? Is it
fsmlabs Bitkeeper repository?

Something like that. This came up a while back (around 2.2.13 I think)
on the -workstation list. I didn't pay enough attention at the time, but
I think it switched from being always little-endian to being
native-endian. At least, I don't recall any x86 folks screaming about
it... ;)

I think without reformatting your only option is to use 'hda=swapdata'.

Probably. If that doesn't work shop around. ;)

What's your version of fdisk ?

Under 2.2.12 dd if=/dev/hda of=xxx bs=512 count=1 and see what comes out.
Can PPCBUG actually boot from these disks ?

I have 2.4.0-test2 running on an MVME2600, look at:

	ftp://vlab1.iram.es/pub/linux-2.4

did not try the MVME2400 yet (they are all in use for real tasks, I'm
waiting for more and have to develop on the 16Mb MVME2600 :-(). But I
only have SCSI disks or NFSRoot.

I have a 2.2.16 kernel compiled but never booted, I could give you R/O
access to my BK trees if you want (but the machine on which they are is
not up 100% of the time).
