[U-Boot] btrfs: data abort with lzo compression (armv7/am335x)

[U-Boot] btrfs: data abort with lzo compression (armv7/am335x)

[Robert Nelson]

Hi Marek,

Having btrfs support in u-boot is awesome!

With u-boot v2018.01-rc1 on our arm target (am335x) BeagleBone family,
we are seeing a data abort with lzo compression.  I'm wondering if
you've seen something similar with your systems:

ignore the "Failed to mount ext2 filesystem..." as we are using the
genric "load" and extX support is built-in too..

loading /boot/vmlinuz-4.9.68-ti-r83 ...
Failed to mount ext2 filesystem...
data abort
pc : [<9ff6eab8>]    lr : [<00000000>]
reloc pc : [<80825ab8>]    lr : [<e08b7000>]
sp : 9df28148  ip : 82020000 fp : 0001f000
r10: 00000d52  r9 : 9df28ed8 r8 : 82001000
r7 : 0001d12c  r6 : 00001000 r5 : 0001d2a6  r4 : 9df53fe2
r3 : 00001000  r2 : 82000000 r1 : 00001000  r0 : 00000000
Flags: nzCv  IRQs off  FIQs on  Mode SVC_32
Resetting CPU ...

resetting ...

the other two options; no compress and zlib are working great in our
single partition setup!

Hi Robert,
can you upload somewhere the whole btrfs image of the partition so that
I can debug this?
Thank you.

Hi Robert,
I just forwarded a patch by Alberto Mollero which should solve this
issue, could you test it and than maybe reply with Tested-by:?
Thanks.
