Processort: AMD Phenom(tm) II X6 1055T Processor (six-core) Ram: 8Gb RHEL6, x86_64. This host doesn't have swap. It hangs up fast. Tomorrow I will have to send a processes state, if it will be interesting for you. With my patch the kernel work fine. I added debug and found that it hangs up in the described case. I suppose that my patch may be incorrect, but the problem exists and we should do something. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
