@Andi OK so it still trips but at least the dump is longer now:

Some Ideas and thoughts about the new Bitwig 5.2 beta. Compressor+ things, OVER clipper and the new Shift Register in action.

@Andi Hey, running drm-tip really does fix any issues. I tried to play for about 20 minutes so it is not like very comprehensive test but in the past things have failed with 2-5 minutes so at least to the right direction.

@ptesarik @timojyrinki @vbabka i dare to say that me having bugzilla account is overall benefit of opensuse because i actually like finding at least ideas for the root cause before reporting anything :-)

@ptesarik @timojyrinki @vbabka this was is not a bug per se because TPM2 boot is not yet a "stable feature" (or is it?) but more like needed precursory step to make that happen.

@ptesarik @timojyrinki @vbabka I put this also here. I did mean to report this but just shows the extra steps one needs to accomplish to get a fully wayland system in Tumbleweed: https://social.kernel.org/notice/AgTCtsiojJvg17ry9w

@ptesarik @vbabka the more recent issue was this but i’m still working on the root cause (just haven’t had yet time to spin): https://social.kernel.org/notice/AhAkgNAoOXUOD2ns4u

In this case it could be either or both upstream and downstream issue but I’m not sure. @timojyrinki said that perhaps xe driver is not in use but now that i checked:

$ lsmod|grep i915
i915                 4202496  69
i2c_algo_bit           20480  2 xe,i915
drm_buddy              20480  2 xe,i915
ttm                   110592  3 drm_ttm_helper,xe,i915
drm_display_helper    245760  2 xe,i915
cec                    90112  3 drm_display_helper,xe,i915
video                  77824  4 asus_wmi,asus_nb_wmi,xe,i915

I’m not a graphics driver expert but for me it looks based on loaded modules that OpenSUSE does actually select XE driver correctly but I could also understand something incorrectly. On this issue I’ll compile drm-tip as suggested in the thread and hopefully make some further conclusions.

The other issue I need to backtrack that from my mastodon spam :-)

@cloud_manul i think this should be readable from earlier comments.

@ptesarik @vbabka please denote that i've tried to change the password few times without success. sign on works otherwise. e.g. forums do work.

@vbabka @ptesarik not super critical but i might already have two bugs to report. can wait until there is time to check what is the problem :-)

@vbabka @ptesarik yeah, i sent email to admin address but no answer. obviously could have ended to junk mail so probably should retry.

Alastair captures one of the biggest problems with the current RISC-V spec. When I looked into this a while back I was (almost) shocked at the lack of rigor and state of the tooling. I say almost because I expected it, but was still sad. Read his blog.

Incredible research at BlackHat Asia today by Tong Liu and team from the Institute of Information Engineering, Chinese Academy of Sciences (在iie.ac.cn 的电子邮件经过验证)

A dozen+ RCEs on popular LLM framework libraries like LangChain and LlamaIndex - used in lots of chat-assisted apps including GitHub. These guys got a reverse shell in two prompts, and even managed to exploit SetUID for full root on the underlying VM!

@kernellogger @archlinux @fedora @opensuse I.e. I'm just peeking and poking and not fully understanding what is going on. Apologies for my ignorance :-) But if there are open proposals whatnot on this I'd for sure want to be in the loop.

True, I want to be in the loop with this for sure!
