I have the same problem on Fedora 39 on Talos. Restarting doesn't work. You have to turn the machine off and on. I got used to it

No, it's a full Talos II but with one CPU. When I feel that the hardware is already inefficient I will buy a second CPU
So far the only program that is too slow on Talos is Firefox

« on: April 28, 2024, 04:16:40 am »Is fast reboot on or off?
I have "Auto boot -> Disabled" in the Petitboot configuration, but I haven't changed that since I started using Talos.
I guess it shouldn't make a difference since rebooting worked fine on older kernels?

What worries me most is the very large variance in SSD performance from version to version. Once it is 4.5 GB/s and the next time it can be even less than 1 GB/s. The best was in versions 6.2.x, there the SSD reading speed often exceeded 6 GB/s.
BTW.Does a machine reboot work properly in Fedora 40? With me on Fedora 39 since kernel 6.6.x, the system crashes after reboot, turns the fans on to the max and I have no video signal on the HDMI of the embedded card. I have to turn off Talos II from the Power button and turn it on again.

Operating Systems and Porting / Unexpected suspend of Fedora 39 on Talos II
« on: January 15, 2024, 01:42:26 am »
After switching to the 6.6.9-200 kernel, I started getting unexpected system transitions to the SUSPEND state and then I could not restore the system to normal operation other than by shutting it down and turning it back on.
I found the solution quite easily, this affliction happens on Fedora on different platforms. The problem is solved by executing the following commands:

Over the past four days on kernel 6.6.9-200, I have made more than a dozen attempts to connect various devices to USB ports and the situation has not repeated.

On the kernel 6.6.8-200.fc39.ppc64le I have recently had similar instances of reboots but they occurred when connecting a device to USB, printer, iPad. On kernel 6.6.9-200.fc39.ppc64le it has been correct for two days.

Firmware / Adventures in reverse engineering broadcom nic firmware

Unlocking a system with 100% open source firmware
Quote
In an era where vendors increasingly seek to use proprietary software in the devices around us to exert control over their users, the desire for open source software has expanded to the firmware that allows our machines to function, and platforms which individuals can trust and control have never been more important. However, changes to hardware platforms in recent years such as the Intel ME, vendor-supplied binary blobs and vendor-signed firmware images have repeatedly set back efforts to create open source firmware for the computers we use. The release of Power servers with 99% open source firmware excited many who had been searching for a computer they could trust, but one proprietary firmware blob remained: that of the Ethernet controller. This is the story of how that blob was reverse engineered and replaced with an open source replacement, delivering the first machine with desktop-class performance and 100% open source firmware in many years.
This talk is about how I reverse engineered the final remaining firmware blob on the Talos II/Blackbird POWER9 systems, enabling it to be replaced with an open source replacement, in an intensive reverse engineering effort that spanned several years.
The talk will begin by introducing the open source firmware movement and its practical and ethical motivations, and note the obstacles to delivering fully open source firmware for contemporary x86 and other platforms and explaining the motive behind the project, before moving onto a more technical discussion of the adventure of firmware reverse engineering and the obstacles encountered.
Subjects I intend to cover include: how the original proprietary firmware was reverse engineered from scratch with only limited knowledge of device internals; the long history of Broadcom NIC architecture and its evolution over time; the tools that had to be developed to enable the device probing, testing and reversing process; the story of a horrifying but necessary detour into reversing x86 real mode code and the novel methodology used to aid reversing; how modern NICs allow BMCs in servers to share network ports with the host, and the security hazards this creates; and how fully open source firmware was created legally using a clean room process.
This talk will be accessible to audiences unfamiliar with POWER9 or the open source firmware community, but is also intended to cover some new ground and be of interest to those familiar with the project. The talk will mainly be of interest to those interested in open source firmware and issues such as owner control and the security and auditability issues caused by proprietary firmware, and to those interested in reverse engineering.

I think I need to hurry up, a while ago I had another crash. I wasn't doing anything in particular I was listening to music on YT and reading Twitter in Firefox. The worst part is that my FreeBSD in Qemu VM has destroyed again...

Yes, I'm considering it but I'm a little afraid to mess something up. I've never done it and my Talos II is my critical resource at the moment.
