Systems: A-EON AmigaOne X1000 and X5000 with Radeon HD6970 graphics

The biggest problem is, that I don't have time for bisecting and fixing 
this issue.

Cheers,
Christian

Oh dear, there is another issue after the latest PowerPC updates. The 
X5000 doesn't boot anymore.

Error messages:

Oops: Exeption in kernel node, sig: 4 [#1]
...
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004

---

Unfortunately we have two issues at the same time. We are knocked out 
and unfortunately I don't have any time for bisecting.

Hi All,

Our FSL P50xx machines don't boot anymore because of IRQ issues. [1]

Please check the IRQ changes in the latest PowerPC updates 5.14-1. [2]

Thanks,
Christian

This looks like mtmsrd in the 64e code. I think this should fix it.

QEMU does not seem to trap on this, maybe something to improve.

Thanks,
Nick

Hi Nick,

Thanks a lot for your patch! We will test it as soon as possible. You're 
right that this issue doesn't exist in a virtual e5500 QEMU machine.

Have a nice day,
Christian

With a patch to qemu to make it take an illegal instruction on mtmsrd I 
can reproduce basically what you have, and this patch makes it work. I
think this is the best short term fix.

Nick

Hi Nick,

Your patch works (see patch below)! Many thanks for your help! We tested 
it on an A-EON AmigaOne X5000/20 and in a virtual e5500 QEMU machine today.

Screenshots:
