> Is it allowed to call a tsleep() from inside a timer int?

Absolutely not.  tsleep() is only valid from in process context.  The
timer interrupt are in interrupt-context and so you aren't allowed to
sleep.

Either you will need to use timeout() or arrange for this processing
to be done in process context.
