Did you check the Bluetooth?  I don't know if this chip has it or if
it's an independent chip on this board, but if Linux is leaving it
powered up but not properly configured you could have issues.

I had already disabled it via hciconfig, without any effect on the problem.

Based on your suggestion I also checked BT_REG_ON, which was not being
affected by hciconfig. On AP6255 I believe it is active high, so I
brought it low to disable bluetooth, confirmed with a scope, and the
problem is still there.

Thanks for the suggestion anyway!
