Just attach the http link should be sufficient.

2017-08-01 Thread Tommy Giesler
I have sent a message to the mailing list.

You are correct. When blacklisting the module everything is working fine
again.

Can you maybe also tell me how do I properly link this bug report to the
mailing list?

Fedora does not have module sm750fb:
# CONFIG_FB_SM750 is not set

Please file escalate the issue to linux-fb mailing list [1].

In the interim, blacklisting the module should make it work like Fedora.

Maybe some config changed when v4.10 -> v4.11?
Can you provide the kernel config from the fedora server with linux 4.11?

[Bug 1707641] Re: Sunix 2D VGA controller causes kernel panic and crash on boot

2017-07-31 Thread Tommy Giesler
Yes, exactly. There is no issue with Kernel 4.10 (16.04 HWE or 17.04).
Current 17.10 Kernel does not boot properly. Unfortunately there are no
logs, even on persistent journald. The OS freezes after switching from
initramfs to real rootfs.

Any hints what logs I could try to gather to pinpoint this issue?

Do you mean there's no such issue on 4.10? There's no change on sm750fb
between 4.10 and 4.11 though...
