I have also this stall problem on a 3 years old machine using an Asus P2L97 mobo. It has an IDE disk on first ata channel and an atapi cdrom on the second one, plus a SCSI disk. There is a ~ 30s delay at boot probing the ata controller. This never occured under 3.* and began with 4.0 I have emailed the info to S.S. but the "bug" was never solved. Here are the relevant dmesg lines: atapci0: port 0xd800-0xd80f at device 4.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 ad0: 1222MB [2484/16/63] at ata0-master WDMA2 acd0: CDROM at ata1-master using PIO3 There are also some ata resetting messages in the logs but not much and they seem innocuous. -- Michel Talon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
