Quite possibly it's the regression tracked in #8001 if it only started failing more or less recently.
This is a new machine.
By checking the boot log, I was able to see that near the end of the log, 'intel_extreme: uninit()' and 'intel_extreme: close()' are called. I would expect functions with those names to be called during shutdown, not at the end of startup. So either these two function calls are part of the problem, and I need guidance on what to look for next, or else someone with a different sense for function naming wrote the driver API (and I still need guidance on what to look for next).Yes, these are called during shutdown of the driver. So for some reason the driver isn't used any longer, i.e. due to the accelerant using it failed to initialize properly and getting shutdown as well.
I'm not seeing those particular messages any longer. Perhaps when I saw them I was looking at a syslog from a boot when I had fail-safe video mode enabled. Would that cause this kind of shutdown?
I used the built-in log viewer to find this information. Is there any way to copy the in-memory buffer that holds the boot log onto a file? Can I dd it from a device? If so, which device and from what offset?What do you mean exactly? The built-in log viewer as in the "syslog" command of KDL? There's a way you can store that to a FAT formated USB stick from the bootloader. Otherwise just copy the syslog file as mentioned by Adrien.
Yes, that's the file I wanted. Storing it this way is easier than manually copying. I'm going to put a copy of the entire syslog on a ticket, but here are the lines that seem relevant to video issues. The ones that seem most suspicious to me are the DDC failures, which are followed by EDID failures. (Not that I know what DDC or EDID are, but the word 'failure' seems ominous.)
