Kernel config
altanative easy reproduce method: % ./hackbench 105 process 1000 this parameter mean consume all physical memory, but no use any swap. (please adjust your test environment) I guess the cause of bug is current linux VM can't memory reclaim under interrupt context. thus, when interrupt happend under memory reclaim running, it cause kmalloc(GFP_ATOMIC) failure. I working on fixed it now. but it need a bit long time... Hi Kosaki, thanks for the report and your effort. Please keep us updates on your work. Is this still an issue with a recent kernel? |
