Installed kernel-smp-2.4.0-0.99.21.i686 from rawhide. At boot, after "loading aic7xxx", I get "NMI watchdog detected lockup on CPU 1", a stack trace, and a register dump. That's all, folks. Rebuilt initrd with aic7xxx_old driver, kernel boots fine. Folks, instead of moving aic7xxx to aic7xxx_old, and then installing a brand new driver as aic7xxx, doesn't it make much more sense just to install the brand new driver as "aic7xxx_new"? Otherwise this is going to nail a whole bunch of folks, on upgrade. This is an Abit BP-6 dual-Celery motherboard, with onboard SCSI. Attachment follows.

This defect is considered MUST-FIX for Florence Release-Candidate #1
I tried 2.4.0-0.99.23 smp from rawhide and it bombs also but the up version bott OK. This looks similar to or the same as 24874. It is interesting the regular 2.4.0-0.99.11smp that came in beta3 (fisher) works OK.
The aic7xxx driver has been reverted from the Adaptec driver to my driver (plus an update to my driver). If you still have problems with the aic7xxx driver after the next kernel release, then please reopen a new bug citing what problems the aic7xxx-5.2.2 driver is having.
