assertion failure in libata-core

assertion failure in libata-core

[Bram Stolk]

Hi,


When enabling atapi, I got the following assertion failure:

Assertion failed! qc->flags &
ATA_QCFLAG_ACTIVE,drivers/scsi/libata-core.c,ata_qc_complete,line=3232

This is when booting my 2.6.14-rc5 kernel with two sata devices:
a maxtor hd, and a plextor dvd writer.

assertion failure in libata-core

[Bram Stolk]

Hello,


I've been trying very hard to get my sata dvd burner to work.
It is a plextor PX-716SA.

I tried the following kernels:

linux-2.6.14-rc5
linux-2.6.14
linux-2.6.14-rc5-mm1 (contains sil24 support)

All with the same result: assertion failure.

Assertion failed! qc->flags &
ATA_QCFLAG_ACTIVE,drivers/scsi/libata-core.c,ata_qc_complete,line=3232

Now, my board has 2 sata interfaces: one from intel,
and one from Sillicon Image.

If I use libata.atapi_enabled=1 and connect the drive to the
intel sata, I get the assertion mentioned above.

If I connect the drive to the sil sata, it is not detected,
and I get this error:
sata_sil24 version 0.22
ACPI: PCI Interrupt 0000:05:00.0[A] -> GSI 19 (level, low) -> IRQ 19
PCI: Setting latency timer of device 0000:05:00.0 to 64
ata5: SATA max UDMA/100 cmd 0xF8838000 ctl 0x0 bmdma 0x0 irq 19
ata6: SATA max UDMA/100 cmd 0xF883A000 ctl 0x0 bmdma 0x0 irq 19
ata5: no device found (phy stat 00000000)
scsi4 : sata_sil24
sata_sil24 ata6: error interrupt on port1
   stat=0x80000001 irq=0xb60002 cmd_err=1 sstatus=0x113 serror=0x0
sata_sil24 ata6: resetting controller...
scsi5 : sata_sil24

How can I use this SATA DVD drive under linux on sata-ahci or sata-sil24?

thanks,

   Bram Stolk

Wait until we fix ATAPI, alas....

Your feedback here helps, though.
