Grigoriy Strokin wrote/schrieb (Friday, March 31, 2000): | While the bug wiping out filesystems on machines with Apollo MVP3 when ATA | driver is in UDMA mode is being fixed, I suppose there at least should be some | note added to /usr/src/UPDATING, so that another users do not loss | all their data and have to reinitialize /usr and restore it from backup, as I | had to do? | | Something like that: | | If you use the Apollo MVP3 chipset, it is STRONGLY | recommended that you disable the use of DMA mode in ATA drivers | BEFORE you try to boot the system after `make installkernel'. | Add the following line: | /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio | to the very beginning of your /etc/rc, | ~root/.profile and ~root/.login. | Be warned that if you don't disable the DMA mode, | all your filesystems may be corrupted because | of a bug in the driver that is still being fixed. | Please excuse if this was mentioned before (I did not follow this thread very closely), but isn't _not_ using options ATA_ENABLE_ATAPI_DMA enough as a measure of precaution? This is from LINT: # ATA_ENABLE_ATAPI_DMA: enable DMA on ATAPI device, since many ATAPI # devices claim to support DMA but doesn't actually work, this is # not enabled as default.
