> What else does SCSI LLD driver need to changed? There are several scsi controllers that handle pci error recovery. For example, look at drivers/scsi/ipr.c, search for struct pci_error_handlers. The callback routines there deal with reseting the driver after an error has been found. I've posted patches in the past for the symbios driver; I suppose it is time to clean them up and resubmit them again; they are not in the kernel yet. I recently posted patches for the Emulex lpfc fibre channel scsi card, google for the subject line "[PATCH] lpfc: add PCI error recovery support" to see what the patch looks like. All of this work was done on powerpc systems. I have only a vague idea of how this works on PC-class Intel platforms. --linas - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
