Cute error message but it appears just before my machine

SPI controller which lspci says is PCI-X but is actually
PCIe.
I get that with 2 different tape drives (LTO-1 and LTO-3)
whose true identities are hidden behind badge engineering,
Tandberg data perhaps? Anyway both seem to have a major
problem with the LOG SENSE command and the Tape Alert
page in particular.
The lockup occurs with both a Debian Lenny standard kernel
(lk 2.6.26-2-686) and a kernel.org lk 2.6.30 .
So the problem has been around for a while ...
There is nothing other than the 53c1030 and a single tape
drive on the SCSI bus. So there is no good reason to lock
up the machine for any SCSI related error.
LSI just reworked the code that does this doorbell handling for the
2.6.31 merge window could you see if 2.6.31-rc2 is still exhibiting the
problem?
Yes it is.
The controller is a LSI20320IE and the main chip appears
to be a LSI53C1020A A1.
