Hi all, During FreeBSD 6.2 installation, the process failed because of errors like the one below: READ_DMA UDMA .... ICRC error LBA=37505132 I managed to install by setting hw.ata.ata_dma=0 at boot time but the same errors occur after installation and at boot time so I had to put hw.ata.ata_dma=0 in loader.conf and now the system is working. I checked my hard disk which a 80GB Western Digital+ thoroughly and there were no errors reported (using fsck in single user mode). Also I used to install Fedora Linux on this disk without any problems. It looks that disabling DMA caused my disk to work with lower performance. Am I right? If yes, are there any solutions to eliminate those READ_DMA errors while DMA is enabled? Thanks in advance, Bahman PS: Motherboard: ASUS A7V8X-X CPU: Athlon XP 2500 at 1833MHz $ uname -ai FreeBSD attila 6.2-RELEASE FreeBSD 6.2-RELEASE #0: Fri Jan 12 10:40:27 UTC 2007 root@dessler.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386 GENERIC
