I'm pleased to report that since upgrading from nvidia-current (270.18-0ubuntu1~maverick~xup1) to 270.29-0ubuntu1~maverick~xup2 the pesky "NVRM: os_raise_smp_barrier(), invalid context!" no longer appear in my system log.
@Ivan Kravchenko: I also experienced the error messages with the 260.19.06 driver.
