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.
