20.04 Server on RaspBerryPi 4B does not finish boot and stops at "spi-bmc2835 fe204000.spi: could not get clk: -517"

Question

I've installed an Ubuntu Server 20.04 on a SD-card running NextCloud. Now, after a reboot it refuses to finish boot. I see:

Net: eth0: ethernet@7d580000
starting USB...
No working controllers found

Then the console refreshes and I see:

[   4.673...] spi-bmc2835 fe204000.spi: could not get clk: -517

That stayes forever and I have no clue how to fix that. Usually I would simply recreate the SD-card and start on new, but in this case I would loose my NextCloud config and data. That is no real drama, but it would take time...

Thanx for any help.

Answer 1

Sorry that I can't help with any productive answer. But it turned out that the SD-card is broken. There is no way around installing it on new.

Answer 2

I have same trouble. finally, i found that problem is the power . change the power from 5V1A to 5V2A, it works.
