Hi All,
I just updated kernel 4.14 within OpenWRT from 4.14.224 to 4.14.229
Booting it shows the splat below on each run. [1]
It seems there are 2 patches regarding flexcan which were introduced in
4.14.226
--> ce59ffca5c49 ("can: flexcan: enable RX FIFO after FRZ/HALT valid")
--> bb7c9039a396 ("can: flexcan: assert FRZ bit in flexcan_chip_freeze()")
Reverting these fixes the splat.
This patch should fix the problem:
47c5e474bc1e can: flexcan: flexcan_chip_freeze(): fix chip freeze for missing
bitrate
Greg, can you pick this up for v4.14?
regards,
Marc
Checking kernels 4.4 & 4.9 shows that this fix is also missing over there.
Marc,
Can you confirm that it's also required for these?
Thanks,
Koen
