I didn't see any reply to the request to see the debug output from
the patch.  So here is the output when it is applied to kernel 2.4.2:

Nope it won't (just checked). I'll produce a patch for this
tomorrow, I know what's going on. Is this an old SCSI drive?

Interesting, does audio volume control work if you play an audio cd?

Could you try with this patch, so maybe we can get some hints as to what
is going on?

Re: vmware 2.0.3, kernel 2.4.0 and a cdrom

[Martin Tessun]

Hi,

I have the same problem. But if I say my CD-RW is the cdrom all works as 
expected (/dev/scd1).

Also the capabilities aren't correct I think:


Jan 14 21:26:31 worf kernel: sr0: scsi3-mmc drive: 0x/0x writer cd/rw caddy

for my CDROM; it is a TEAC-CDROM without caddy, but tray and has a 
read-speed of 42. It is NOT a writer.

The writer seems to be recognized correctly (again a TEAC-CDRW):

Jan 14 21:26:31 worf kernel: sr1: scsi3-mmc drive: 24x/24x writer cd/rw 
xa/form2 cdda tray

Only the write-speed isn't correct (it can only write 8x not 24x)

As I have no time in the moment to dig this down further, I just write 
this for information.

Btw I'm using kernel 2.4.0 with reiserfs and NVIDIA patch.

Bye
Martin

vmware 2.0.3, kernel 2.4.0 and a cdrom

[Martin Maciaszek]

[-- Attachment #1: Type: text/plain, Size: 610 bytes --]

Since I installed Kernel 2.4.0 VMware is no longer able to
recognize my cdrom drive. VMware shows a dialog box on power up
with following content:
[...]
CDROM: '/dev/scd0' exists, but does not appear tobe a CDROM device.

Error connecting the CDROM device
[...]

At the same time my syslog records the following message:
Jan 13 21:49:57 nexus kernel: sr0: CDROM (ioctl) reports ILLEGAL REQUEST.

I tried 2.2.18 and VMware recognized the cdrom drive.

Any hints?

Cheers
Martin
