Now I wonder if it's my IDE controller which has problems.

READ_DMA Error
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 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/GENERIC i386 GENERIC ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
FAILURE - READ_DMA error
Hello, Just a quick question, on this one server ( custom server in a 1U supermicro case p4 3.0ghz 1gb ram) I keep on getting HD errors… I replaced many drives and I always get the same error. I just replaced my motherboard and went to a SATA drive from IDE… In the middle of a FreeBSD install... I got the following error: FAILURE - READ_DMA What can the issue be? -- No virus found in this outgoing message. Checked by AVG Free Edition.
