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 ?
Not that I know.
I did know exactly when this happens years ago.
The backtrace as such will not help you as the panic happens much
later than the cause.
IIRC the basic problem was that the realignment code only fixes
a single missalignment, while theres a chance for more then one.
Verify nfs_realign in nfsserver and nfsclient to get an idea.
If you are interested - I've found a (non-working) patch that I wrote
for it, but the intention of it should be clear.
Sure. This is an nfsd specific problem,
Or does nfsclient have issues as well ?
I'll get a pr going to make sure that the issue
is documented, and possibly narrowed down enough for
other people to start painting a bikeshed about how
it should be fixed.
