Interesting.  We're seeing occassional true hangs (no oops or other info
logged, the system just hangs.  SysRq *does* work, though).

In our case, only the internal disk is on the aic7xxx controller, the
tape drives are driven through fibre channel on a QLA2300 adapter.

Assuming you're actually getting any error or debug info.  I'm very very
familiar with Red Hat's Land of Misfit Toys, er, um, Bugzilla.

Thanks for the info!
