Ending a boot log with
platform 3f202000.mmc: deferred probe pending
is already a nice hint about the problem. Sometimes there is a more detailed error indicator available, add that to the output.
Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> --- Hello,
it's only compile tested, I created that patch while remote debugging an issue by an irc user who provided the kernel log of a hung boot ending in such output.
Best regards Uwe
