In the log, I > only see ata3.00 is dying. Isn't there any log from different port? There is no other log from the different port such as the enablement of ata2, it's strange. I forgot to say that this case appear when the "OnChip SATA Type" is "Native IDE"(SATA device ID is 4390) in BIOS. But when I set "OnChip SATA type" into "AHCI" mode(SATA device ID 4391), the hotplug can work, and the device name will be changed from "scd0" to "scd1" during the hotplug. The log messages are attached at the end of this mail. But I need the reasonable explanation to the failure under "Native IDE" mode. Thanks Shane ====== plug SATA ODD to a different SATA port under AHCI mode, can work ======== Dec 18 18:40:07 linux-i276 kernel: ata3: exception Emask 0x10 SAct 0x0 SErr 0x90200 action 0xe frozen Dec 18 18:40:07 linux-i276 kernel: ata3: irq_stat 0x00400000 , <PHY RDY changed> Dec 18 18:40:07 linux-i276 kernel: ata3: hard resetting link Dec 18 18:40:08 linux-i276 kernel: ata3: SATA link down (SStatus 0 SControl 310) Dec 18 18:40:08 linux-i276 kernel: ata3: failed to recover some devices, retrying in 5 secs Dec 18 18:40:13 linux-i276 kernel: ata3: hard resetting link Dec 18 18:40:13 linux-i276 kernel: ata3: SATA link down (SStatus 0 SControl 310) Dec 18 18:40:13 linux-i276 kernel: ata3.00: limiting speed to UDMA/33:PIO2 Dec 18 18:40:13 linux-i276 kernel: ata3: failed to recover some devices, retrying in 5 secs Dec 18 18:40:15 linux-i276 kernel: ata2: exception Emask 0x10 SAct 0x0 SErr 0x40c0000 action 0xa frozen Dec 18 18:40:15 linux-i276 kernel: ata2: irq_stat 0x00000040 , <connection status changed> Dec 18 18:40:16 linux-i276 kernel: ata2: soft resetting link Dec 18 18:40:16 linux-i276 kernel: ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) Dec 18 18:40:16 linux-i276 kernel: ata2.00: ATAPI: TSSTcorp CDDVDW TS-H653B, CM01, max UDMA/33 Dec 18 18:40:16 linux-i276 kernel: ata2.00: configured for UDMA/33 Dec 18 18:40:16 linux-i276 kernel: ata2: EH complete Dec 18 18:40:16 linux-i276 kernel: scsi 1:0:0:0: CD-ROM TSSTcorp CDDVDW TS-H653B CM01 PQ: 0 ANSI: 5 Dec 18 18:40:16 linux-i276 kernel: sr1: scsi3-mmc drive: 40x/40x writer dvd-ram cd/rw xa/form2 cdda tray Dec 18 18:40:16 linux-i276 kernel: sr 1:0:0:0: Attached scsi CD-ROM sr1 Dec 18 18:40:16 linux-i276 kernel: sr 1:0:0:0: Attached scsi generic sg2 type 5 Dec 18 18:40:18 linux-i276 kernel: ata3: hard resetting link Dec 18 18:40:19 linux-i276 kernel: ata3: SATA link down (SStatus 0 SControl 310) Dec 18 18:40:19 linux-i276 kernel: ata3.00: disabled Dec 18 18:40:19 linux-i276 kernel: ata3: EH complete Dec 18 18:40:19 linux-i276 kernel: ata3.00: detaching (SCSI 2:0:0:0) Dec 18 18:40:19 linux-i276 kernel: scsi 2:0:0:0: rejecting I/O to dead device Dec 18 18:40:43 linux-i276 syslog-ng[2291]: last message repeated 6 times - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
