Yesterday I installed the above referenced kernel on two Raspberry PIs, a 3B+ and a 3B. I
also installed it on a BeagleBone Black and a Hummingboard2 (nxp i.mx6 Quad CPU).
On the BeagleBone Black and the Hummingboard, no problems at all, so this appears to be
specific to the Raspberry PI platform or CPU. The Raspberry PI's are both actually
running, but I noticed that top tells me that the load average is 4.0. But these things
are not actually doing anything. Top does not show any process using more than 0.7% CPU
and that it tells me that each core is nearly 100% idle. dmesg is not giving me any
significant errors.
I have worked at finding the problem for a few hours and have not found a lot. But here
is what I have found:
If I reboot to kernel 4.20.16, the problem goes away.
When booted into kernel 5.0.3 dmesg gives this line:
[ 16.342693] systemd[1]: Mounting Kernel Debug File System...
but I see nothing that indicated why this might be happening.
Anyone else try kernel 5.0.3 on a Raspberry Pi? Any thoughts on where to look for the
problem?
Thanks very much!
