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. Doug Gilbert
