Hi,
sdhci_fsl_fdt0: Desired SD/MMC freq: 50000000, actual: 50000000; base 700000000 prescale 1 divisor 14
GEOM: new disk sdda0
sdda0 at sdhci_slot0 bus 0 scbus0 target 0 lun 0
sdda0: Relative addr: 00000002
Card features: <MMC Memory High-Capacity>
Card random: unblocking device.
GEOM: new disk sdda0boot0
memory OCR: 00ff8080
sdda0: Serial Number .......
sdda0: MMCHC .................................. by 17 0x0000
GEOM: new disk sdda0boot1
uhub0: 2 ports with 2 removable, self powered
at which point basically anything hangs. In auto-boot it is
before/during file-system checks.
In single user mode camcontrol devlist will show sdda0
but
root@:/ # gpart show sdda0
load: 6.06 cmd: gpart 24 [g_waitfor_event] 1.28r 0.00u 0.00s 0% 2088k
{forever}
Unclear at which point I broke to debugger and this is where it seems to
hang:
