After upgrading my Soekris Net 6501-70 (amd64) to this revision the
system is unusable. Basically all programs produce a "Segmentation
fault (core dumped)":

pid 856 (ls), jid 0, uid 1001: exited on signal 11 (core dumped)
pid 857 (ls), jid 0, uid 1001: exited on signal 11 (core dumped)
pid 858 (bsdtar), jid 0, uid 0: exited on signal 11 (core dumped)
pid 859 (sh), jid 0, uid 0: exited on signal 11 (core dumped)
pid 876 (dmesg), jid 0, uid 1001: exited on signal 11 (core dumped)
pid 877 (su), jid 0, uid 0: exited on signal 11
pid 880 (more), jid 0, uid 1001: exited on signal 11 (core dumped)
pid 885 (sudo), jid 0, uid 0: exited on signal 11
