First the problem: the LED on my SCSI card has not been working. This
finally got annoying enough that I went in and hacked the source. This is
in kernel 2.0.35. At line 4201 in ncr53c8xx.c, I did the following:
if ((driver_setup.led_pin ||
(nvram && nvram->type == SCSI_NCR_SYMBIOS_NVRAM)) /*&&
!(np->sv_gpcntl & 0x01)*/)
np->features |= FE_LED0;
Commenting out that one test made it work.
Now then, on to the details.
My card is an Intraserver IT-3140U. The chip is the Symbios 53c875. The
card uses the Symbios BIOS and Symbios-format NVRAM. I wouldn't be
surprised if it was a Symbios card, actually, and sold by somebody else.
The machine is a DEC Alpha 21164a with a PC164LX motherboard running kernel
2.0.35 plus appropriate Alpha patches. The driver comments say "4 June
1998, version 2.6n".
More information is below if you need it.
I has tried using "ncr53c8xx=led:1" in the boot string in MILO but this had
no effect (it would be nice if the driver would mention this when it boots).
So I made that one hack and it now works fine. I am not saying that you
should use that hack in your code, but some fix is desirable.
Here is more info about the system should it be necessary. This info comes
after running it with that test commented out:
