I was able to setup nfsroot, and boot postmarketos (with root read/only, but that's good enough for debugging). Then I was (finally!) able to run dmesg, and that tells me: [ 0.816040] mousedev: PS/2 mouse device common for all mice [ 0.817657] input: TWL4030 Keypad as /devices/platform/68000000.ocp/48070000.i2c/i2c-0/0-0048/48070000.i2c:twl@4= 8:keypad/input/input0 [ 0.820800] i2c /dev entries driver [ 0.830261] omap_wdt: OMAP Watchdog Timer Rev 0x31: initial timeout 60 sec [ 0.836212] omap_hsmmc 480b4000.mmc: RX DMA channel request failed [ 0.840026] ledtrig-cpu: registered to indicate activity on CPUs [ 0.840789] omap-aes 480c5000.aes: OMAP AES hw accel rev: 2.6 [ 0.840942] omap-aes 480c5000.aes: Unable to request in DMA channel [ 0.841644] omap-aes 480c5000.aes: will run requests pump with realtime priority Kernel 4.13-rc2. I'm now trying: +++ b/.config -CONFIG_MMC_OMAP_HS=3Dy +# CONFIG_MMC_OMAP_HS is not set With that, error is gone, but so is MMC driver, so... not good. Any ideas?
