This now looks to be failing relatively frequently (about every other flight),
and I'd rather suspect it to point at a hypervisor issue than a Linux one.
Looking at the log I found

(XEN) d5v0: vGICD: unhandled word write 0xffffffff to ICACTIVER0
(XEN) arch/arm/traps.c:1985:d5v1 HSR=0x80000006 pc=00000000 gva=0 
gpa=0000000000000000
(XEN) arch/arm/traps.c:1985:d5v1 HSR=0x80000006 pc=0x00000c gva=0xc 
gpa=0x0000000000000c
(XEN) arch/arm/traps.c:1985:d5v1 HSR=0x80000006 pc=0x00000c gva=0xc 
gpa=0x0000000000000c

with the last two messages then repeated over and over, many dozen times a
second. Which makes me wonder whether that verbosity alone is causing a
problem.
