TWO Netra T1 AC200 unable to boot. Don't see the SCSI bus or network interface

2007-12-24 21:30:00

Hello,

I have a problem with *TWO* Netra T1 AC200 machines. Both of them
show exactly the same problem after about a month running, and they
have failed simultaneously.

When resetting, the machines are unable to boot, giving a "Data
Access Exception" after probing the memory slots.

If I try to do a "probe-scsi-all" in this state, I get an "ok"
answer just in less than a second, and it does nothing. The device
tree does *not* show the scsi or net subsystems:

If I use "probe-all" it seems to detect the scsi and net devices,

And the scsi bus now works.

But I try to boot and I get a "Fast Data Access MMU MIss"

-------

These machines have been working without problems for about a month.
In fact, one of them has Oracle 9i installed. Any ideas? I cannot
find an OpenBoot manual for 4.0 version.

It seems strange because two machines are showing exactly the same
symptoms... Of course I have tried reverting the environment
variables to the default values, with no success.

Any ideas? Of course, I will summarize to the list. BTW, where can I
find documentation for OpenBoot 4.0?

Thank you,

Borja.
