To start debugging this, I really need a stack trace from a crash. There
should be one as part of the panic message. Alternatively, if you can
script a workload that crashes UML, send that, and I'll debug it here.

The host is i386 or x86_64?
TLS support is complete on i386, so fidding with /lib/tls shouldn't be
necessary.
However, TLS problems wouldn't cause a kernel crash.
