Description Kamil Pawlowski 2008-06-23 19:13:27 EDT
I have Abit AN52 with Athlon X2 6000. To even start system I must use pci=nomsi
kernel argument. 

When system boot:

Comment 1 Kamil Pawlowski 2008-06-23 19:16:39 EDT
PS. Previous I write "cd", of course I mean DVD-RW drive

# hdparm /dev/cdrom 
/dev/cdrom:
 IO_support    =  0 (default) 
16-bit)
 HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device
 HDIO_GET_DMA failed: Inappropriate ioctl for device
 HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device
 readonly      =  0 (off)
 readahead     = 256 (on)
 HDIO_GETGEO failed: Inappropriate ioctl for device

This is not good, it look like my drive work like DMA33 with no UDMA

MSI is disabled by default at boot in Fedora 9.

Does the drive work after that?

It is using UDMA/33, that is indeed UDMA and probably as fast as it will go.
hdparm does not know how to set or get DMA settings for libata; it will use the
fastest DMA setting the drive is capable of unless overridden at driver load time.
Comment 3 Chuck Ebbert 2008-06-23 23:32:09 EDT
The problem should be fixed by commit 15fe982e429e0e6b7466719acb6cfd9dbfe47f0c
