hpt366 driver oops or panic with HighPoint RocketRAID 1520 SATA (HPT372N)

[Johan Palmqvist <johan.palmqvist@inap.se>]

When used with a HighPoint RocketRAID 1520 SATA (HPT372N) the hpt366 
driver, compiled as a module, oops'es on loading. If the driver is 
compiled into the kernel it causes a kernel panic on boot while 
detecting the card. Kernels tested: 2.6.13.2, 2.6.13.4 and 2.6.14. 
Please CC any answers to me since I'm not on the list.
