memtest
While conducting the memory test, correctable read data errors may be encountered,
indicating memory integrity problems. However, if hardware error reporting is
disabled, the CPU corrects the correctable errors without reporting them. To alleviate
this problem, the mcheck parameter must specify the machine check conditions
while running the memory test.
Device drivers that use main memory for DMA access while the memory test is
running may cause unpredictable results. To prevent the memory test from
conflicting with the device drivers, the stop_drivers parameter must be set to a
nonzero value.
