Re: Using an HSZ50

[Michael Mackey <michael-mackey@uiowa.edu>]

I have used an HSZ70 with RedHat 7.2.

On boot, I got the same kernel log messages, up to the error reading 
sdg's partition table.

I also saw a lot of unhandled interrupts, especially while any mmapped 
file io was going on (typically whilst running dump or fsck).

You can find a more complete description at  http://alpha.crl.dec.com in 
the Bugzilla database (bug #40).

I think it is a problem in the interrupt handling code for the qlogic 
driver - the HSZ controllers use some undocumented interrupts.
