------- Additional Comments From Jens.Maurer@gmx.net  2004-01-28 22:31 -------
I've just checked in a rework of the low-level mgmt queue handling that may or
may not fix your problem.  At least it kills islpci_mgt_queue so the kernel
message will show a different symbol. :-)

Please try it out and report your findings here.
