Description Andreas Färber 2019-05-31 10:24:33 UTC

Booting the Kernel:HEAD 5.2-rc2 kernel on, e.g., a Raspberry Pi 3 Model B I get:

[    4.983797] module dm_mod: overflow in relocation type 258 val feefd014
...
[    6.731417] module phy_generic: overflow in relocation type 258 val d3d7172d
[  OK  ] Started udev Coldplug all Devices.
[    6.802239] i2c-bcm2835 3f805000.i2c: Could not read clock-frequency property
[    6.803812] module mmc_core: overflow in relocation type 258 val d9c33bb1
[    6.820504] module usbcore: overflow in relocation type 258 val 9f68f2cc
[    6.922416] module mmc_core: overflow in relocation type 258 val d9c33bb1
[    6.981875] module mmc_core: overflow in relocation type 258 val d9c33bb1
[  OK  ] Reached target Remote File Systems (Pre).
[  OK  ] Reached target Remote File Systems.

This then leads to the rootfs on SD card not being found.

I think Torsten had the same issue which got fixed by:
3fd00beb14a5 ("arm64/module: revert to unsigned interpretation of ABS16/32 relocations")

Indeed, it should fix it. Please retry with 5.2-rc3 (once available in Kernel:HEAD).

Comment 3 Michal Kubeček 2019-06-03 16:15:32 UTC

Kernel:HEAD won't get 5.2-rc3 until tomorrow (I came to the office later so
that I didn't update the branch before OBS submission deadline) but QA/aarch64
build of kernel-obs-qa in IBS project Devel:Kernel:master which used to fail
with error like in the initial description now succeeds with 5.2-rc3 kernel.

Comment 4 Michal Kubeček 2019-06-10 11:30:09 UTC

Going to close later this week unless someone can reproduce with 5.2-rc3 or
newer.

Comment 5 Andreas Färber 2019-06-10 11:36:36 UTC

On the two boards tested so far, boot is now working.

Comment 6 Andreas Färber 2019-06-10 11:37:32 UTC

Tested on Raspberry Pi 3 Model B and Nano Pi K2.
