The Banana Pi still doesn't work properly in kernel 5.9.6. I am not in a position to check schematics and to fix DTs. Look at git log for arch/arm/boot/dts/sun7i-a20-bananapi.dts, that would be you, Chen-Yu Tsai and Maxime Ripard. Is there anything I can do to help debugging?

Since Banana Pi have same PHY, it might cause issue there too. Reverting this commit does actually help here. Will there be a fix in Greg's kernel releases? Thank you for helping!

[linux-sunxi] Banana Pi, Kernel 5.9, packet loss and bad network connectivity
Hi, when I boot my Banana Pi (with Debian buster installed) with kernel 5.9, the network interface doesn't work too well. Packet loss of more than 50 %, machine nearly unuseable. Going back to 5.8.13 fixes the issue, going forward to 5.9 again makes the issue reappear. Does anybody have a good guess what to try first before going the "implant 5.8.13 stmmac driver to 5.9, maybe bisect" route? Greetings Marc -- - Marc Haber | "I don't trust Computers.

[linux-sunxi] Re: Linux 5.1 not booting on banana Pi
Bisecting the kernel identified 4e7babba30d820c4195b1d58cf51dce3c22ecf2b which is unfortunately too complex to validly roll back (adding Eric and Herbert, Authors and Off-Signers to Cc). As a short-term workaround, setting CONFIG_CRYPTO_MANAGER_DISABLE_TESTS seems to help.

[linux-sunxi] No USB with kernel 4.12
Hi,
I am using Debian Linux on a row of Banana Pi's with a self-built kernel
from the mainline archive.
Since 4.12, my USB is not working any more. Devices are not seen, lsusb
returns silently with a return code of 1. I guess that the offending
part of an strace lsusb is:
socket(AF_NETLINK, SOCK_RAW|SOCK_CLOEXEC|SOCK_NONBLOCK, NETLINK_KOBJECT_UEVENT)
= 3
setsockopt(3, SOL_SOCKET, SO_ATTACH_FILTER, "\n\0\0\0T0\345\276", 8) = 0
bind(3, {sa_family=AF_NETLINK, nl_pid=0, nl_groups=0x02}, 12) = 0
getsockname(3, {sa_family=AF_NETLINK, nl_pid=26668, nl_groups=0x02}, [12])
= 0
setsockopt(3, SOL_SOCKET, SO_PASSCRED, [1], 4) = 0 fcntl64(3, F_GETFL)
= 0x802 (flags O_RDWR|O_NONBLOCK)
fcntl64(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
[pid 26668] recvmsg(3, {msg_namelen=128}, 0) = -1 EAGAIN (Resource temporarily
unavailable)
The modules do all load, but somehow the subsystem is not initialized
correctly.
I tried bisecting the kernel between v4.11 and v4.12, and between v4.11
and v4.12-rc1, and ended up twice with the first commit being
# first bad commit: [df6f37225d62316f8505f10ef1099ee40fa3978b] net: realtek:
8139cp: use new api ethtool_{get|set}_link_ksettings
which is a commit that has nothing to do with USB. In fact, the 8139
driver is not even enabled in the kernel I build.
I cannot make any sense from this. Can you?
Greetings
Marc
