hello all, i have freebsd8.2 on my system with journaled gpt partitions. occasionally, i see the below errors in startup and system doesn't boot correctly. if i restart system, it boot normally and every thing is ok. these errors are: ad3: WARNING - WRITE_DMA requeued due to channel reset LBA=635411 ad3: WARNING - READ_DMA requeued due to channel reset LBA=635411 ata1: FAILURE - already active DMA on this device ata1: setting up DMA failed ad3: WARNING - WRITE_DMA requeued due to channel reset LBA=635411 ata1: FAILURE - already active DMA on this device
and these errors are shown repeatedly. i have two question: does journaling cause to happen these errors? and if i set hw.ata.ata_dma to 0, is it resolve the problem? if yes, has it any side effect or not? any comments or hints are really appreciated.
