Hello, There is a problem with recent ATA drivers on (at least) AMD64 with 4 GB of RAM, which can be triggered by synchronizing a geom mirror provider to another one (or generally a bigger disk I/O, I guess). The machine dies instantly with the following: GEOM_MIRROR: Device hars: rebuilding provider ad6. ad6: setting up DMA failed ad6: setting up DMA failed This is true either on RELENG_6 and on HEAD as of today. There are two workarounds: - use the ata driver from RELENG_6 which is not older than 2005.10.08 - set hw.physmem smaller than 4G Are there any chances to resolve this issue? Thank you. ps: there was some discussion about this: http://marc.theaimsgroup.com/?l=freebsd-amd64&m=113034973432742&w=2 where Søren said it might be busdma, not the ata driver and Scott promised to look into that. -- Attila Nagy e-mail: Attila.Nagy_at_fsn.hu Free Software Network (FSN.HU) phone: +3630 306 6758 ISOs: http://www.fsn.hu/?f=downloadReceived on Mon Nov 28 2005 - 13:12:53 UTC
