RPi4 showing errors in dmesg, NETDEV WATCHDOG: eth0 (bcmgenet): transmit queue 0 timed out

I am experiencing this on RPi4B running OpenWRT which does not use the RPi Foundation kernel, it is mainline. I first noticed it on 5.10.84 but it presists on 5.10.87.

You are only (maybe) concerned at 85C as this is where throttling occurs.

Re: Moving Linux Kernel to 5.15

The Pi is a cell phone. Doubt you would see any speed differences. Main point is that the kernel provides the code, not another package.

Re: Moving Linux Kernel to 5.15

For NTFS you just mount the target partition: mount -t ntfs3 /dev/foo1 /mnt/bar I believe udisks does not yet support it though, although Issue#932 linked to some merged code 4 days ago. As I type this, the last tagged release was on 29-Sept. I don't know about smb, kernel docs ? Tried googling?

Re: Moving Linux Kernel to 5.15

@dom - Will you be updating the next branch of userland as well? I believe this will be needed to bring the 64-bit firmware into parity with 5.15.0, no? You may have to explain what you think needs changing? Kernel is pretty much independent of firmware and userland. The rpi-update firmware and use...

Re: bluetooth needs dtparam=krnbt=on on aarch64 but not armv7h

Maybe it has something to do with using mini-UART for aarch64 vs armv7h? https://github.com/archlinuxarm/PKGBUILDs/blob/master/alarm/uboot-raspberrypi/PKGBUILD#L68 uboot-raspberrypi is only installed with linux-aarch64 (the vanilla mainline kernel). As I test, I added "enable_uart=1" /boo...

Re: bluetooth needs dtparam=krnbt=on on aarch64 but not armv7h

@macmpi - Those files you referenced are not provided by Arch ARM at all. They exist in the Arch User Repository (AUR) which is an unofficial source of packages contributed by users. Again, to be clear: Arch ARM armv7h does not supply hciattach nor does aarch64. Whatever is causing the expected beha...

Re: bluetooth needs dtparam=krnbt=on on aarch64 but not armv7h

My knowledge of it is heavily based on the Arch wiki page for bluetooth. Arch (and Arch ARM) both use the bluez and bluez-utils packages. The included bluetooth.service does all the work. It seems to be calling /usr/lib/bluetooth/bluetoothd

Re: bluetooth needs dtparam=krnbt=on on aarch64 but not armv7h

Thanks for the reply, Phil. For Arch ARM aarch64, I believe it is 100% 64-bit user land. One difference I can think of that might actually be irrelevant since as I mentioned, booting 64-bit with the vanilla upstream kernel works is that the firmware package is mostly built from userland whereas the ...

Thus far I have only verified functionality with dtparam=krnbt=on added to config.txt. What is the hciattach to which you refer? Glad to try it.

Re: bluetooth needs dtparam=krnbt=on on aarch64 but not armv7h

Yeah, this distro for RPi's is technically "Arch ARM" where "Arch Linux" is the parent project but not the same distro. "Arch Linux" implies x86_64. In any case, this is on Arch ARM.

Re: bluetooth needs dtparam=krnbt=on on aarch64 but not armv7h

Thanks for the replies, all. I know that bluetooth is working on 64-bit RPiOS without this overlay. Interestingly, if I Arch ARM is booted using the vanilla kernel (currently 5.14.x series), bluetooth just works. I would like to identify the breakage and fix it.

bluetooth needs dtparam=krnbt=on on aarch64 but not armv7h

Bluetooth on RPi4 or RPi400 under Arch ARM aarch64 does not work without the addition of dtparam=krnbt=on By contrast arm7h does not need it. I am wondering why. Of course, bluetooth is working on 64-bit RPiOS without this overlay. Interestingly, if I Arch ARM is booted using the vanilla kernel (cur...

Not sure which distro you're running but on Arch ARM, qbittorrent-nox supplies a service for you, qbittorrent-nox@.service.

Re: Optimal distcc settings when compiling an RPi

I was thinking more about how to setup the build itself. MAKEFLAGS and DISTCC_HOSTS. I am experimenting with some settings and will share the results when finished, just wanted to see if anyone else had any experiences.
