I tested it on wd driver on 3.1-RELEASE, but I heard that same accident happens on ata driver on 4.0-CURRENT. Read-only mount works OK, but writing to R/W mounted filesystem crashes the entire filesystem immediately. >How-To-Repeat: Always. >Fix: I have no idea. Ad-hoc solution can be disabling IDE DMA option on this chipset. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
