That's correct. We removed support for the 8xx devices from ncr53c8xx leaving it to drive the non-PCI 720 chip only. > But sym53c8xx gives me this when I try to insert it while the attached > scanner is ON: > > PCI: Found IRQ 9 for device 0000:02:09.0 > sym0: <810> rev 0x1 at pci 0000:02:09.0 irq 9 > sym0: No NVRAM, ID 7, Fast-10, SE, parity checking > CACHE TEST FAILED: timeout. > sym0: CACHE INCORRECTLY CONFIGURED. > sym0: giving up ... > > The exactly same results I seen when I tried this driver under a 2.4 > kernel. Are you saying that it works fine when the scanner isn't plugged in, or is turned off? > I've googled that this dumb scanner doesn't report parity and that > disappoints the sym53c8xx driver, but I failed to find an appropriate > option to turn parity checking off. Furthermore, I've also googled some > info that sym53c8xx just doesn't support 53c810 chips at all. I removed the option to disable parity checking. Looks like I should reinstate it. I have an 810 card here that works fine, so that information is out of date. - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
