There are some PCI root bridge issues still unresolved, but they usually

You could try a kernel with DIAGNOSTIC/DEBUG/LOCK_DEBUG added (slow!), and
see if this catches anything. Do you have a special workload to trigger the
I have investigated since my first mail and I think that memory was
defective. This server ran with 8 * 1 GB. When I have replaced this
memory by 8 * 256 MB, it runs fine.
Other question : does NetBSD adjust CPU frequency ? I have found
information about acpi drivers, but nothing about a sparc64 driver.
No, is it even possible on that hardware?
It is possible (Linux can slow down CPU when it is idle). CPU can run
at nominal frequency, half and 1/32 frequency. I'm trying to patch
kernel to add cpufreq data in cpu_info structure.
Also make sure you have Julian's latest changes to dev/tda.c, it will make
an audible difference on Blade 1000/2000.
Yes I know ;-)
