I have posted a patch that will fix the counters oops. So far, I could not reproduce the icache-hygiene problem, did you use hardware large page support or software emulation? But I probably noticed a similar one:
map_high_truncate_2 (32): FAIL mmap() 1: Cannot allocate memory
That one should be because of the 31-bit address space layout on s390, as it tries to mmap too much (1.5GB).
I also noticed that task-size-overrun (64) seems to hang up on my system, I can only continue after ctrl+c, can you verify that?
Thanks, Gerald
