--- Comment #2 from Bjorn Helgaas <bhelgaas@google.com> ---
I think this is a 3w-9xxx driver defect, so I'm reassigning to SCSI.  Here's my
rationale (from the email thread mentioned above):

  ... twa_probe() looks strange to me.  The other drivers I looked at
  do all their PCI initialization before the scsi_host_alloc() /
  scsi_add_host() / scsi_scan_host() stuff.  But twa_probe() has PCI
  stuff scattered around between those three SCSI calls.  In particular,
  it does the MSI setup way down near the end, after scsi_add_host(),
  which seems like just the sort of thing that could explain this problem.

Let me know if this seems like the wrong thing to do.
