mptspi: Unexpected doorbell active!
Cute error message but it appears just before my machine locks solid. It looks like it is coming from a LSI 53c1030 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 .
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.

So the problem has been around for a while ...

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?
Thanks,

Yes it is.
The controller is a LSI20320IE and the main chip appears to be a LSI53C1020A A1.

Can you provide dmesg log with log level enable to 0x8188.
"echo 0x8188 > /sys/class/scsi_host/hostX/debug_level"
Thanks,
Kashyap

It's probably not relevant to the problem, but I'm pretty sure 53c1030 SPI is a PCI-X device. I supported this driver for HP's IA64 (e.g rx2600) machines starting around 2001 or 2002 (before PCIe was available). Can you dump the lspci output that claims this is a PCIe device?

I believe there is a 3rd party that makes PCIe 1030 boards. They are not directly marketed by LSI.
The boards consist of a PCIe to PCI-X bridge and a regular 1030 chip.
