nForce / sata_nv not detecting SATA CDROM [SOLVED]

[fronck]

Hi,

I've got a problem with detection of my SATA DVD+R/CR+RW combo on my nForce3 350 based system.

The setup is such that I have two SATA devices: My harddisk, off which the Gentoo install runs just find, and my CDROM, which Linux does not detect.

I find it a bit wierd that it would detect one and not the other. They're located on separate SATA controllers that both sit on the motherboard.

At startup, dmesg goes:

Code: Select all

ata1: SATA max UDMA/133 cmd 0x9F0 ctl 0xBF2 bmdma 0xE900 irq 185
ata2: SATA max UDMA/133 cmd 0x970 ctl 0xB72 bmdma 0xE908 irq 185
ata1: dev 0 cfg 49:2f00 82:346b 83:7d01 84:4003 85:3469 86:3c01 87:4003 88:407f
ata1: dev 0 ATA, max UDMA/133, 390721968 sectors: lba48
ata1: dev 0 configured for UDMA/133
scsi0 : sata_nv
Uhhuh. NMI received for unknown reason 3d.
Dazed and confused, but trying to continue
Do you have a strange power saving mode enabled?

- So it seems to be that both SATA controllers are detected, but only one is probed to detec attached drives..

Any ideas on how to mount the CDROM?

TIA

I'm not sure, but maybe you need SCSI-CDROM support?

[racoontje]

Probably.

I have now enabled the following to no avail:

Code: Select all

 --- SCSI device support
                     [*]   legacy /proc/scsi/ support
                     ---   SCSI support type (disk, tape, CD-ROM)
                         <*>   SCSI disk support 
                         < >   SCSI tape support                                                                        
                         < >   SCSI OnStream SC-x0 tape support
                         <*>   SCSI CDROM support                                                                       
                     [*]     Enable vendor-specific extensions (for SCSI CDROM)                                    
                         <*>   SCSI generic support                                                                     
                    ---   Some SCSI devices (e.g. CD jukebox) support multiple LUNs                                
                     [ ]   Probe all LUNs on each SCSI device                                                       
                     [ ]   Verbose SCSI error reporting (kernel size +=12K)                                         
                     [ ]   SCSI logging facility

Still the system does not see my SATA CD drive. Any other hints I might try out?

Yeah, that seems to be the problem.
I stumbled upon this solution somewhere else as well and tried doing the #define.

This, however is not advisable with the 2.6.9 kernel, as it does make the kernel detect the CD drive during startup, but also makes it hang immediately afterwards.

I'll post my findings once I give the 2.6.10 kernel a whirl. Thanks for your help!

PROBLEM SOLVED

Cookbook solution:
As described in http://forums.gentoo.org/viewtopic.php? ... 24#1916224:

• Upgrade kernel to 2.6.10
• Find the file libata.h (in /usr/include/linux or /usr/src/linux-2.6.10<release>/include/linux/)
• Edit the line near the top of the file:

  Code: Select all

  #undef ATA_ENABLE_ATAPI /* define to enable ATAPI support */

  change it to

  Code: Select all

  #define ATA_ENABLE_ATAPI /* define to enable ATAPI support */

• And finally: Enable SCSI CDROM support in kernel

Thanks to everybody who helped!
