I now know what the problem is.

In drivers/scsi/aha152x.c, there is an array of two scsi hosts:
        static struct Scsi_Host *aha152x_host[2];
There is also the aha152x_probe_one method.

The problem is that each re-insert of the card creates a new 'host' via aha152x_probe_one,
which increments the registered_count variable. This variable is used as an index into the afore-
mentioned 2-element host array. When registered_count is 2 or greater we're in no-man's land,
hence the crashes. I'm currently testing a fix for this, which I hope to post soon.

That's a workaround IMO, not the proper fix.

It turns out I was trying to remove the driver before doing 'pccardctl eject'.

It seems that removing the driver after ejecting make the problem go away:
I ejected and re-inserted the card six times with no crash.

I'll continue testing just to make sure.

Something is going very wrong here.  At time .637 it says it is
adapter number 13 (aha152x13.)  Then at .650 it thinks it's
adapter nr. 22856 (!)  Looks like some kind of pointer to the
hostdata is corrupted.

Can you rmmod the driver after removing the card and see if that
helps?

Kernel panic when re-inserting Adaptec PCMCIA card

[Alex Davis]

The card is an Adaptec SlimSCSI 1460D Fast SCSI card.
I frequently get this panic when re-inserting the card:

I always typed "pccardctl eject" before removing the card.

Can test patches if necessary.
