I've had this issue for over a year and never (I think?) got a good version, so while it might be a regression, it's not a recent one. > How stable in terms of clocking is the configuration that you are using? > I could try to fire up a similar test on a Pi4 at home, or use one of > our 72112 systems which is the closest we have to a Pi4 and see if that > happens there as well. I'm not really sure about the clocking. Is there any clock you want to look at in particular? My setup is fairly simple: the firmware and kernel are loaded over TFTP and the rootfs is mounted over NFS, and the crash always occur around init start, so I guess when it actually starts to transmit a decent amount of data?
