Ok, let's see what kind of errors does your machine report. It looks like benign GART TLB walk errors but let's verify that first. Can you apply the following patchlet and re-trigger the problem: -- diff --git a/drivers/edac/edac_mce_amd.c b/drivers/edac/edac_mce_amd.c index 713ed7d..fc4a68e 100644 --- a/drivers/edac/edac_mce_amd.c +++ b/drivers/edac/edac_mce_amd.c @@ -311,9 +311,12 @@ void amd_decode_nb_mce(int node_id, struct err_regs *regs, int handle_errors) if (regs->nbsh & K8_NBSH_ERR_CPU_VAL) pr_cont(", core: %u\n", (u8)(regs->nbsh & 0xf)); } else { - pr_cont(", core: %d\n", ilog2((regs->nbsh & 0xf))); + pr_cont(", core: %d\n", fls(regs->nbsh & 0xf) - 1); } + pr_err("%s: NBSL: 0x%08x, NBSL: 0x%08x\n", + __func__, regs->nbsl, regs->nbsh); + pr_emerg("%s.\n", EXT_ERR_MSG(xec)); Thanks. -- Regards/Gruss, Boris. -- 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/
