Hello,
recently, a kernel patch series was posted to fix issues with HugeTLB
on UltraSPARC (sun4u) machines [1]. I have built a test Debian kernel
which includes the patch and uploaded it to [2].
Could someone test this kernel and report back whether it causes any
regressions and also whether it possible fixes the stability issues
we're seeing on UltraSPARC machines with newer kernels?
I gave the kernel a spin on my T2000 with Niagara. Sorry, took a while,
but needed a spare evening, possibility to shut down, connect LIOM cable
to another system, ssh.. etc etc.
I left it running a couple of hours, did run git on big repositories
several time, run aptitude, compiled stuff on 32 cores. Exported GUI
stuff thorugh X11.
No issues noted, no regressions at a first test.
Furthermore, previous kernel usually crashed itself on a hot reboot,
requiring always a cold start (this caused me a lot of trouble testing
in the past). I cycled a couple of reboots without issues.
No certainty, but for me this kernel is better than the previous one!
I did not run explicit stress test. I remember there was one floating
around on this list that did lock up my system after 10 minutes or so.
would be interesting to try.
Riccardo
