http://bugzilla.kernel.org/show_bug.cgi?id=11735 ------- Comment #2 from bumble.bee@xxxxxxxxx 2008-10-10 17:20 ------- Hi Alan, I'd love to do just that. Maybe if this thing can perform in PIO mode it won't matter that there's no DMA. I've built a kernel and initrd for both delkin_cb and pata_ninja32. # hdparm -t /dev/hde /dev/hde: Timing buffered disk reads: 10 MB in 3.35 seconds = 2.98 MB/sec # hdparm -t /dev/sdb /dev/sdb: Timing buffered disk reads: 6 MB in 3.27 seconds = 1.84 MB/sec The dmesg seems to indicate PIO4: pccard: CardBus card inserted into slot 0 PCI: 0000:02:00.0 reg 10 io port: [0, 1f] PCI: 0000:02:00.0 reg 14 32bit mmio: [0, fff] pata_ninja32 0000:02:00.0: enabling device (0000 -> 0003) pata_ninja32 0000:02:00.0: PCI INT A -> Link[LNKD] -> GSI 11 (level, low) -> IRQ 11 pata_ninja32 0000:02:00.0: setting latency timer to 64 scsi2 : pata_ninja32 ata3: PATA max PIO4 irq 11 ata3.00: ATA-0: TRANSCEND, 20070831, max UDMA/66 ata3.00: 31326208 sectors, multi 0: LBA ata3.00: configured for PIO4 ata3.00: configured for PIO4 ata3: EH complete scsi 2:0:0:0: Direct-Access ATA TRANSCEND 2007 PQ: 0 ANSI: 5 I'm afraid pata_ninja32 doesn't do much better with suspend. After resuming, top shows me kacpi_notify using about 50% cpu, kacpid using ~42%, scsi_eh_1 about 0.3% and the rest is in "wa" state. Reads from the disk still don't return. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- 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
