zalon/ncr53c720 (linux-2.6.0-test5-pa22) broken on C110

Hi all,

I read well the thread about the pb on K460 and so try to test it on my C110 model but is failed to boot:
2.6.0-test5-pa22

I am sure there is no hw pb because after that test I can always reboot with 2.6.0-test5-PA6:

Can somebody could help me to find patches (step by step) applied on this driver from -pa6 to -pa22?

Thanks in advance,
Joel

This is good to hear.

Yes. Could you start with -pa18 (or -pa20)?
http://cvs.parisc-linux.org/download/linux-2.6/patch-2.6.0-test5-pa18.gz
(or cvs up -rCVS260_TEST5_PA18)

The driver is rev 1.5 in -test5-pa6. rev 1.6 is in -test5-pa18. After -test5-pa20, we don't have anyautotagged stuff, but let's start with -pa18.

Thanks Matthew,
(why didn't I think myself ;) )

Ok I will look and advise you,

So break is in patch...-pa14-pa18 (if I am lucky I could check it next week :) )

Joel

OK; we don't need the stack dump since that's already fixed in the top of tree.

OK. Can you try applying the following patch to -pa18? Note that applying this patch to the top of the tree will not work (you'd need an additional patch for that).
