Subject: qla2xxx hba crashes with older 2310 cards

Hi,

I've seen some chatter about the qla2xxx driver but not paid attention, so
I'm sorry if this is a known issue.  I've got an older qlogic hba, and recent
drivers don't seem to play nice with it.  I've got the latest firmware from
qlogic's web site.  I'm using a 2.6.21-rc6 kernel from Steve Whitehouse's
-nmw git tree.  Reverting to an older driver (but same kernel) and it works.
The current driver gives this:

Starting udev: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000

The older driver that works properly gives this:

Is this a known problem, or is someone working to fix it?
