Apparently the SCSI Parallel transport class domain validation cable width detection wasn't working, leading to cases where controllers with damaged cables would end up hanging the system (the reported one was an aic79xx controller, but the potential is there for all SPI based systems). This bug would *only* affect systems whose cable integrity or connectors were compromised, so it isn't life threatening to every SCSI Parallel installation, but the consequence of running into it is a system hang. The fix is available here: master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git The short changelog is: James Bottomley (1): scsi_transport_spi: fix domain validation failure from incorrect width setting And the diffstat: scsi_transport_spi.c | 28 ++++++++++++++++++++++------ 1 file changed, 22 insertions(+), 6 deletions(-) James
