I tried the same with an other nfs server (using dill as nfs server this
time - system description is in my 1st mail, same mount options like /
mnt/files). And guess what? dill rebooted immediate... dd came never
back, gave no output
dill's dmesg shows me:
fatal kernel trap:
trap entry = 0x4 (unaligned access fault)
faulting va = 0xfffffc0006b6f44d
opcode = 0x28
register = 0x5
pc = 0xfffffc0000541e08
ra = 0xfffffc0000541df4
sp = 0xfffffe000a0f9b70
usp = 0x11ffea80
curthread = 0xfffffc000f91ee10
pid = 343, comm = nfsd
This is absolutely known - TCP/nfs has bugs in realigning packets.
Don't use TCP on strong aligned architectures.
Still a pr with a proper backtrace would be nice.
Or does one exist already ?
