Re: Kernel 4.3

I tested the latest git kernel today because it was added a lot of new irq source code 2 days ago.

Latest irq patch: fadb97b089563da69ba326f9fea6399d071462b2

Unfortunately I couldn't patch this new irq source code with our patch.

Therefore I compiled the latest git kernel without our irq patches. Unfortunately our kernel doesn't boot with the new irq system:

Code: Select all

Oops: Kernel access of bad area, sig: 11 [#1]

.sb600_8259_cascade+0x4c/0xac (unreliable)
.schedule+0x74/0x9c (unreliable)

I was able to remove the new irq commit with:

Code: Select all

git revert fadb97b089563da69ba326f9fea6399d071462b2 -m 1
Output:

Code: Select all

217 files changed, 573 insertions(+), 482 deletions(-)
After that I was able to patch it with our Nemo patch 4.3-5.

Mailing list announcement

Download: vmlinux-4.3-rc2-AMIGA_one_X1000.tar.bz2

The latest RC gives me IRQ errors, and in the few times it doesn't I get stuck on login screen not showing. Reverting to RC2 fixed this. On RC2 I'm still having networking issues as it relates to simultaneous uses and log in and out without rebooting which is manifested also in disconnections.

Hi Srtest,

Thank you for testing. I have to investigate the IRQ problems. The main problem is, that the new IRQ system doesn't work with our Nemo patch. Therefore I replaced it with the old kernel 4.1 IRQ system.

Cheers,

Christian

Usually where I have seen the Systemd kernel modules errors. Even when those weren't noted the login screen didn't came up.
