Sorry, i didn't find any info about Netra 200. Is it a smp system?

I don't if netra 200 is available in smp configurations. However, mine is single CPU.

sparc people: Any ideas here?

A netra 200 will not boot, it produces this kernel error in early bootup:

PER_CPU: Invalid layout, ptr[fffff80020160000] shift[10] base[fffff8001f972000]

[Comment 4 Gustavo Zacarias (RETIRED) 2006-02-10 09:18:31 UTC]

Nope, the netra 200s are UP with a UltraSPARC-IIe.
Which OBP version do you have, and did you try upgrading to the latest?

[Comment 5 Carlos Silva (RETIRED) 2006-02-12 17:08:54 UTC]

huummm.... can you provide your .config file? that error is related to SMP. since the Netra 200 is UP, why do you have SMP activated? Looks like it can cause trouble...

[Comment 6 Gustavo Zacarias (RETIRED) 2006-02-14 07:39:59 UTC]

Actually the livecd kernels are only SMP and there's no reason on sparc64 at least for SMP kernels not to work on UP systems.
I tend to think it's an old buggy OBP, so please specify version or try the latest.

[Comment 7 Daniel Drake (RETIRED) 2006-02-28 07:52:38 UTC]

Please reopen when you have provided info about the OBP.
