Eh?  How'd that happen?

Please send a full report.  Trimmed dmesg output with test2 and test4.

Thanks.

-test4 detects scsi hdds in another order than -test2 does

Make it easy for us please.  What is the difference between these two?  What
bug are we looking for?

with -test2 first found drive is IBM DNES, 2nd - QUANTUM.
with -test4 first found drive is QUANTUM, 2nd - IBM DNES

Re: -test4 detects scsi hdds in another order than -test2 does

[James Bottomley]

I think this is due to the hotplug fixes for the Sym2 driver.  I've cc'd
Mathew Wilcox to confirm,  but basically, I think the test4 order will
be definitive from now on.

In -test4, the sym2 driver has been converted to the pci_driver
API.  That means that the cards are now detected and probed one
after another rather than having the driver search through the pci
list, find the cards in a strange order, then whack them with the
contents of whichever NVRAM is determined to have highest priority
(which causes all kinds of strange behaviour).

In -test2, somehow the cards are discovered in reverse order.  This must
be due to NVRAM as your cards are all of the same type.  So can you try
clearing the NVRAM or configuring the cards to be in the opposite order?
That should make -test2 discover the cards in the same order as -test4.

I assumed everyone who used scsi on Linux was used to the cards appearing
in random order ...

Well, not quite.

After all, the clever hacks like scsi adaptor scan order
boot option, scsihosts=...,  were invented to bring order to the chaos.

The following is my boot command for 2.4.21 kernel.
I folded the long line manually.

  drm=debug root=/dev/sda6 ro vga=3 scsihosts=sym53c8xx:tmscsim
