Bug#516785: Bug #516785: linux-image-2.6.26-1-sparc64-smp: SunFire480R cassini network driver kernel panic
 
Hi,

I can confirm that Debian Squeeze 6.0.4, with kernel
linux-image-2.6.32-5-sparc64-smp, version 2.6.32-41 or
2.6.32-41squeeze2, does not crash anymore. The installation process is
smooth (d-i prompts for a firmware), and the system is working well.
But don't run lshw with this kernel, it may cause panic (#665932).

Aron Xu

Well I can't see any changes that might have fixed this. Maybe there's
a difference between your machine and Hermann's?

Hermann, what was the last kernel version where the cassini driver
worked on this system? You originally reported that the problem started
with 2.6.24 in 'etch-and-a-half'.

The short answer is: never, the driver always crashes the machine after a
short time.

As far as I remember with discussions from davem the driver only worked on UP
machines, which I can't simulate with the Sun Fire 480R as it has 2 CPU/board.
A dual cassini Gigabit RJ45 is build in.

I'm on vanilla 3.2.12 at the moment and will test after easter in the
(not so much) spare time. If anybody with such a machine has it running
I'm interested to hear.

Thanks,
Hermann
