On console and system logs. Freezes can be caused by kernel bugs
and there are a lot of kernel bugs in sparc64 port.
I have systems with wheezy where I saw some corrected ECC (console
and logs).
But the main problem are the freezes - there is some discussion on
the sparc kernel over freezes under io load. So probably some of that
bugs are fixes in the 3.17 rc's > rc1 - will try when time permits.
Maybe, but I haven't see this kind of discussion for a long time.
I cannot test 3.17-rc1 as sun4v support is broken (LSI SAS and cpu
support).
I could potentially test it, but in order for that the happen the Debian
team would have to make sure that usable CD images were being built.
They can't shift the blame for that upstream.
And don't forget that some chipsets (psycho for example) are
buggy. U80 triggers false ECC errors when system runs with 4 GB of RAM.
I was working through spare machines and boards earlier in the year, and
found a disturbing number where POST was reporting Psycho failures which
broke PCI hence ebus etc.
I'd be interested to hear others' experiences: is Psycho known to have a
limited service life?
