ATI RS480-based motherboard: stuck while booting with kernel >= 2.6.15 rc1

From: Carlo E. Prelz

Best regards to all and everyone. I just purchased a new RS480 (Radeon
XPress200)-based motherboard. It is a Sapphire Pure Performance
PP-A9RS480. Mine is equipped with an Athlon64 3200+. I am attaching
the output of lspci -v

When booting with kernels from 2.6.15-rc1 up (tested with 2.6.15-rc1,
2.6.15-rc5, 2.6.15 and 2.6.16-rc1), the boot process freezes after
displaying messages retated to registering io schedulers:

...
...
io scheduler noop registered
io scheduler anticipatory registered
io scheduler deadline registered
io scheduler cfq registered

There is no OOPS of any kind. The disk activity led remains on. With
both 2.6.14 and 2.6.14.6, boot regularly continues with:

Floppy drive(s): fd0 is 1.44M
FDC 0 is a post-1991 82077
loop: loaded (max 8 devices)
pktcdvd: v0.2.0a 2004-07-14 Jens Axboe (axboe@xxxxxxx) and petero2@xxxxxxxxx
nbd: registered device at major 43
...
...

I tried to enable all debug options in configure, but no new message
appears.

Important: I obtain the same result (frozen after "io scheduler cfq
registered") when booting with a 100MB netinst debian sid bootdisk,
downloaded last night. An older (9 month old) Ubuntu bootdisk boots
perfectly. Both cd's are AMD64-specific.

I will be very happy to provide any further info, or to make any
test. Please CC me in your answers if you can.

Carlo
