Dear all, I have a platform PATA chip : JMB368 IDE controller (1-port PATA Host Controller) HDD : TOSHIBA MK1214GAH Use pata_jmicron.ko in linux 2.6.25.4 [ 21.942308] ACPI: PCI Interrupt 0000:05:00.0[A] -> GSI 16 (level, low) -> IRQ 16 [ 21.942571] PCI: Setting latency timer of device 0000:05:00.0 to 64 [ 21.942696] scsi2 : pata_jmicron [ 21.942976] scsi3 : pata_jmicron [ 21.943192] ata1: PATA max UDMA/100 cmd 0xdc00 ctl 0xd880 bmdma 0xd400 irq 16 [ 21.943301] ata2: PATA max UDMA/100 cmd 0xd800 ctl 0xd480 bmdma 0xd408 irq 16 [ 26.959936] ata1: port is slow to respond, please be patient (Status 0xd0) [ 31.804198] ata1: SRST failed (errno=-16) Fail to detect the HDD.

Seems after SRST, the disk needs over 30 seconds to clear its BSY status. Try IDE driver jmicron.ko in 2.6.25.4 [ 44.870518] Uniform Multi-Platform E-IDE driver [ 44.870732] ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx [ 60.096513] JMB: IDE controller (0x197b:0x2368 rev 0x00) at PCI slot 0000:05:00.0 [ 60.096873] ACPI: PCI Interrupt 0000:05:00.0[A] -> GSI 16 (level, low) -> IRQ 16 [ 60.097202] JMB: 100% native mode on irq 16 [ 60.097429] ide0: BM-DMA at 0xd400-0xd407, BIOS settings: hda:DMA, hdb:DMA [ 60.097928] ide1: BM-DMA at 0xd408-0xd40f, BIOS settings: hdc:PIO, hdd:PIO [ 60.098342] Probing IDE interface ide0...

(I guess. :p) Not sure host or device issue. Is it possible to fix the problem? -- Best Regards, Edward -- 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
