I got a new M2 drive for my laptop, and to make my life simpler, I dd'ed my first drive onto it.
Then, my laptop crashed during the copy due to a block IO hang, and when I rebooted, my laptop crashed
as soon as it booted and before it could even display the error.
I had to buy an M2 to USB adapter, put the device into another machine, and it was fine there:
[273396.702695] sds: sds1 sds2 sds3 sds4 sds5 sds6 sds7 sds8
[273396.723778] sd 11:0:0:0: [sds] Attached SCSI disk
[273399.124555] bcache: bch_journal_replay() journal replay done, 29 keys in 3 entries, seq 7367941
[273399.151148] bcache: register_cache() registered cache device sds4
then, back in my laptop, I was able to setup netconsole and confirmed that apparently
having 2 devices with the same bcache signature, causes an immediate crash.
Yes, it's not a supported or expected configuration, but the 2nd device
should be ignored instead of crashing the kernel.
I eventually fixed the problem by dd'ing /dev/zero onto that bcache
partition on another machine, but in the end, that was days lost, and
having to buy and wait for an M2 to USB adapter (yes in hindsight, now
that I know the problem, I could have built a kernel without bcache to
fix the device on that machine, but obviously I didn't know then).
