Hello,
Theo gave a hint to check early console code and I found something curious.
Here is a diff to printf debug...
Index: sxiuart.c

RCS file: /cvs/src/sys/arch/armv7/sunxi/sxiuart.c,v
retrieving revision 1.3
diff -u -p -r1.3 sx
I do believe that this is a pmap issue.
I just got hands on an Allwinner A20 and suffered the same issues:
pool_setlowat crashing randomly, same for ahci and so on.
I believe we are not syncing the PTEs correctly.
Here’s the snippet from PTE_SYNC(), but PTE_SYNC_RANGE() has
the same issue:

Hello,
Here is the log of new image.
Booting with "-c" option, UKC still hangs up.
I hope the log helps debugging.

Hi, here is the log using bsd.SUNXI.umg instead of bsd.rd.SUNXI.img.

"-c" invokes UKC, but hangs up at there.

Hi,

Curiously, -c option in bootargs seems to be ignored.
I tried it both uEnv.txt and U-Boot console. Here is the log.
There is no problem to pass "-c" string to kernel.
What is happening?

Thanks but not worked...
And, Ethernet PHY(RTL8211E) is recognized as ukphy.
I heard that the power of PHY is controlled by GPIO PH23.

What shoud I do pass "boot -c" string to armv7 kernel?
On i386/amd64 bootloader simply type it but armv7 uses U-Boot.
Tweak uEnv.txt?

Kernel did not started... U-Boot says checksum is ok, so maybe
.umg file is not corrupted.

Hi,
I remember that there has been an issue, only seen on Cortex-A7/A15, like the
Allwinner A20.
The fix for that issue is somewhere here[0].
Try this[1] kernel and have a look if it has the same issue or not.
I do not have an A20, so I can’t test it, sorry. But I’ll probably buy

I tried bsd.rd.SUNXI.umg snapshot on Banana Pi, cheap Allwinner A20
board like Raspberry Pi (see http://www.lemaker.org/).
It booted but something wrong. Arch Linux (for Banana Pi) works fine
so I think the board is not broken.
