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.

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?
