Aiee, killing interrupt handler
Kernel panic: Attempted to kill the idle task!
This corresponds to this code in
drivers/scsi/aic7xxx.c:aic7xxx_handle_seqint()
scb->sg_list[0].address =
cpu_to_le32(pci_map_single(p->pdev, sense_buffer,
sizeof(cmd->sense_buffer),
scsi_to_pci_dma_dir(cmd->sc_data_direction)));
hscb->data_pointer = scb->sg_list[0].address;
scb->flags |= SCB_SENSE;
The comments talk about this being a fake command - should the driver has
set direction to one of SCSI_DATA_WRITE/SCSI_DATA_UNKNOWN/SCSI_DATA_READ
manually? I don't know.
Regards,
Tigran.
