[parisc-linux] palo-1.4 broken on 32bit ?

[Helge Deller]

Hi all,

after apt-get upgrading to palo_1.4_hppa.deb it seems, that palo-1.4 isn't able any longer to boot up a 32bit Linux kernel on a 32bit Machine.
I've run several tests on a B180L, and only after downgrading to palo-1.3 I was able to boot again.

Am I the only one seeing this problem ? 
Anyone maybe has an idea what has been changed ?

Well, it works just fine for me:

However, there have been several reports of intermittent failures with
later versions of palo; if you could actually track the issue down, that
would be greatly appreciated.

The current thought is that it's a command line issue (i.e. embedding a
commmand line >128 characters in palo causes failures).

Ok, I will test this tomorrow (the machine is in the office)..

Thanks for the hint,

No - I've been seeing it on the c3600 as well.
I haven't tried 64-bit kernels.
And downgrading iplboot to 1.3 also solves it for me too.

palo 1.3 deb is available here in case someone has upgraded:
	http://iou.parisc-linux.org/~grundler/palo/palo_1.3_hppa.deb

thanks to paul bame for keeping those around.

nope...have to look at palo since it doesn't matter which
kernel I attempt to boot, it doesn't work.

Note that I tried to build palo v1.2 and that failed the same way.
So it's possibly a compiler issue with real-mode code.
(Not that the compiler knows the difference...)

When I last tried to build palo 1.4 the iplboot turned out bigger
(8K, iirc) than the one in the official deb, and mine didn't work.
Didn't have time to figure out why.

Same here on 3750.  Boot fails with

ext2_init: bad magic 0x0

Downgraded, reran palo and the problem is gone.  Command line is >128.
I shortened it a bit but I think this a problem for people using graphics
consoles.

New palo in CVS or a deb for testing/unstable at
http://parisc-linux.org/~bame/palo/palo_1.4heisen_hppa.deb

I'll upload to Debian when someone besides me sees success.

You Rock!  works on my B180.
The b180 failed to boot with palo 1.4 two or three days ago.

thanks!
