Linux 5.1 not booting on banana Pi

[Marc Haber]

Hi,

when I try booting Linux 5.1 on the Banana Pi, it stops with locked up
CPUs:

[ OK ] Started udev Coldplug all Devices.
[ OK ] Started Create Volatile Files and Directories.
[ OK ] Reached target System Time Synchronized.
Starting Update UTMP about System Boot/Shutdown...

Any ideas what the problem could be, and how it could be solved?

Bisecting the kernel identified 4e7babba30d820c4195b1d58cf51dce3c22ecf2b
which is unfortunately too complex to validly roll back (adding Eric and
Herbert, Authors and Off-Signers to Cc).

As a short-term workaround, setting CONFIG_CRYPTO_MANAGER_DISABLE_TESTS
seems to help.

Greetings

Hello

Probably related to sun4i-ss.
I have sent some fixes for it which could resolve that.

You can disable the new tests using CONFIG_CRYPTO_MANAGER_EXTRA_TESTS.

Please also give the latest kernel a try as it has a number of fixes
to the sun4i driver.

Hang also happens with Linux 5.1.1 with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS disabled.

What would the "latest kernel" be? 5.1.1?

I can confirm that applying those four patches to a 5.1.1 tree results
in a bootable and working kernel on the Banana Pi even with the extra
crypto tests enabled.

Thanks for helping!
