Hello linux-block,
I have been working with a fellow Ham Radio operator, Martin CT1IQI, on an upgrade
to an open source SDR radio. The upgrade will replace a pi CM4 with a Raxda CM5.
https://apache-labs.com/al-products/1061/ANAN-G2-Ultra-HF--6M-100W-Ultra-High-Performance-SDR.html
We are progressing very well with that project but have come across an intermittent
issue that we are hoping you may provide some clues on how to fix.
We are using kernel version 6.11.1 under an Armbian OS. This issue doesn't happen
on the Armbian 6.1.75 branch but will happen without any of our changes to 6.11.1.
I have also tested with 6.11.3 and found the same problem.
This issue is a kernel Oops that happens randomly early in boot. Probably 1 out of 10
boots. It will hang if the issue happens.
I wonder if you may have any ideas about it? I have attached a dmesg but it is the dmesg from
after a successful boot as I don't know how to get the dmesg when the Oops happens as the
board is locked up. If there are other methods to get more info to you please let me know.
