>Description:
Machine hangs with Micropolis drives. Using a 6 way ccd hanging off a

machine. shutdown -r now, freezes just after sync disks done.

All drives are old 2.8 GB model 1936

use a Micropolis 1936 drive

same as all the other Micropolis fixes I found in

 This sounds like two separate problems:
 
  - newfs "stops" the machine
  - yet you are till able to do a shutdown -r now, which causes the machine
    to freeze when it hits the cache sync
 
 Can you elaborate a little bit on the problem?
