Thanks for providing the information. Bugzilla bug under discussion: https://bugzilla.kernel.org/ show_bug.cgi? id=217890 I also found fix attempt of which 3rd version somehow went past me: https://lore.kernel.org/all/[email protected]/ Does this or disabling hwrng sort out the issue? I got one other idea too with no empirical basis (just hypothesis): perhaps release memory mapping on suspend could help firmware. Br, Jarkko
Acknowledged. Disabling HWRNG via kernel cmdline failed, and since my research implied that path would require a custom kernel, I shifted my efforts toward forward-porting Mr. Alves's 2024 patch to 7.2.7. It took some work, but I have successfully compiled it and got it booting on my machine. The patch appears to sort out the issue so far, but I'm only 43 hours into the test. As we discussed previously, this bug can take days to manifest, so I will reply again once I cross a week of sleep cycles without a crash. I also have a USB3 debug cable on the way in hope of capturing the hardware state during the power transition. That said, if Mr. Alves's patch continues to work as well as it has so far, there may not be any need for that. Sean
