Minor 2.4.3 Adaptec Driver Problems

Minor 2.4.3 Adaptec Driver Problems

[Earle Nietzel]

I just got 2.4.3 up a running (on Abit BP6 Dual Celeron ) and
it reorderd my SCSI id's. Take a look. I don't like that my ZIP drive
becomes sda because if I ever remove it then I'll @#$% my harddrive dev
mappings again and have to change them again. Adaptec Driver 6.1.5

Upgrade to version 6.1.8 of the aic7xxx driver from here.  This was
fixed just after 6.1.5 was released:

http://people.FreeBSD.org/~gibbs/linux

Use the 2.4.3-pre6 patch.

I upgraded to the level 6.1.8 but It is still booting the scsi generic(sg)
driver before my hard drives. I have verified that I am using Rev 6.1.8 from
dmesg.

I did applied patch 2.4.3-pre6 on a stock 2.4.3 kernel.

ideas?

That's what ext2 volume labels are for.


Bye.

If you use ext2 . . . .

Volume labels dont help for all cases. Its a bug in the 6.1.5 adaptec driver
which (to save Justin pointing it out) is fixed in 6.1.8

Actually, there is a component of this related to link order which is
fixed in the upcoming 6.1.9 driver release.  The 7895, channel B
primary issue, is fixed in 6..1.8.

That is really not a great solution although it's half OK.

Here's why?

You can put labels on all your ext2 partitons but what happens on:
    cdroms
    zip drives
and probably most important:
    swap
but lets just say anything other than ext2 partition.

Also you can't put a LABEL in LILO either.

This is probably great for those people who use ide only, but then again
people who had ide only machines were not affected by v2.4.3!

Good try though!!!

My IDE and AIC7xxx drivers are compiled in to the kernel. I normally conpile
system dependent drivers into the kernel and leave the rest modules when
possible.

In all prior versions of the kernel 2.4.3 I have never had this problem. I
have both 2.4.2 & 2.4.3 and when booting from one to the other 2.4.2 orders
my SCSI id's correctly and 2.4.3 doesn't.

It really wouldn't make a big deal but I consider my cdroms and zip drives
to be removable devices and if I ever decided to remove my zip my scsi ids
will change. Removing a harddrive is not the same as removing a zip!

Are there other people with the same problem?

Earle

If you need any more info don't hesitate to ask.

Yes, I have ide-scsi compiled in for cd-writer, so 2.4.3 did not
boot on my machine (that is, could  not mount anything).

Not nice.
