Interesting. www.zefox.org is the aarch64 that is not configured in config.txt in the normal aarch64 manor. As I've requested before, please test using a config.txt that instead has: QUOTE [all] arm_64bit=3D1 dtparam=3Daudio=3Don,i2c_arm=3Don,spi=3Don dtoverlay=3Dmmc dtoverlay=3Ddisable-bt device_tree_address=3D0x4000 kernel=3Du-boot.bin [pi4] hdmi_safe=3D1 armstub=3Darmstub8-gic.bin # Local addition: [all] force_mac_address=3Db8:27:eb:71:46:4f END QUOTE Please do not use a configuration based in part on armv7 FreeBSD config.txt material any more for the testing activity: Just use the FreeBSD normal aarch64 configuration with the force_mac_address related material added at the end. I want to know if this also fails when powerd is not in use anywhere. [I assume that the "The Pi4 workstation" is the "pi4 RasPiOS workstation". True? Presuming yes: Is the RasPiOS the 64 bit variation? (Just my curiosity.)] Do you run the buildworld on www.zefox.org and such via the tip session on pelorus.zefox.org ? Via an ssh session from the "pi4 RasPiOS workstation" to www.zefox.org ? More generally: A) What runs (if anything) via the tip session started from pelorus.zefox.org ? B) What runs (if anything) via the ssh session connected to www.zefox.org ? A useful test would be to not have the tip command running on polaris.zefox.org and to just use the ssh to www.zfox.org instead to start the buildworld/buildkernel. So: No use of the serial connection when the buildworld is started or during the build(s). Using tip before that but quitting tip before starting to load the RPi4B would be okay for this type of test. The question would be if the: client_loop: send disconnect: Broken pipe still happens. (I'm not claiming that recovery if it fails would be nice. But finding out if it fails looks to be important.) The contrasting useful test would be to start the buildworld from the tip session on polaris.zefox.org and to not have any ssh session to www.zefox.org . The question would be if a failure of some kind still happens. (The tip session does not have a pipe in use as far as I know so the detail for identifying faulure would likely be different.) Another question would be: do both such tests fail? Just one (which)? None? So trying both tests eventually would be important. It is important to have only one of the 2 types of connections in use during the buildworld/buildkernel and such activity for this type of test --and only the one instance of which ever type the active test is for. =3D=3D=3D Mark Millard marklmi at yahoo.com
