My beaglebone-ab does not like this. With this patch applied I end up
with:
[ 2.437316] Waiting for root device /dev/mmcblk0p2...
[ 4.428192] mmc0: card never left busy state
[ 4.432647] mmc0: error -110 whilst initialising SD card
I noticed this after I disabled lock debugging and tracing (syscall tracing
was enabled). Enabling both again makes the error go away.
With debugging + tracing disabled (so the error pops up) and git bisect
I get this commit (daebabd57) reported.
A diff between a good/bad bootlog (with lock-debug + tracing switched
off):
