[Bug 561619] [NEW] [Lucid] pata_pdc2027x: Invalid PLL input clock 0kHz, give up

Mon Apr 12 16:17:28 UTC 2010

Public bug reported:

Lucid is unable to access disk drives on a Promise FastTrak TX2000
controller (PDC20271). This is a serious regression. No drives are
found.

The pata_pdc2027x module loads but reports a 0Khz PLL clock:

A7M266D kernel: [  878.820515] pata_pdc2027x 0000:03:06.0: PCI INT A disabled
A7M266D kernel: [  886.889501] pata_pdc2027x 0000:03:06.0: version 1.0
A7M266D kernel: [  886.889603] pata_pdc2027x 0000:03:06.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
A7M266D kernel: [  886.988894] pata_pdc2027x 0000:03:06.0: PLL input clock 0 kHz
A7M266D kernel: [  886.988899] pata_pdc2027x: Invalid PLL input clock 0kHz, give up!
A7M266D kernel: [  886.989104] scsi4 : pata_pdc2027x
A7M266D kernel: [  886.989574] scsi5 : pata_pdc2027x
A7M266D kernel: [  886.989647] ata5: PATA max UDMA/133 mmio i256 at 0x9000 cmd 0xa7c0 irq 17
A7M266D kernel: [  886.989653] ata6: PATA max UDMA/133 mmio i256 at 0x9000 cmd 0xa5c0 irq 17
A7M266D kernel: [  887.164082] pata_pdc2027x: 40-conductor cable detected on port 0
A7M266D kernel: [  887.320118] pata_pdc2027x: 40-conductor cable detected on port 1

Those final two messages about 40-conductor cables are incorrect too -
both ports have high-quality known-good 80-conductor cables.

The key problem is " Invalid PLL input clock 0kHz" which is probably the
root cause of all other symptoms.
