 |
|
OK, so I moved from kernel 2.6.24 to 2.6.26 today (2.6.25 had issues for me, forgot which). Everything is working fine. The only glitch so far is that I had a DVD on my bay, and now Gentoo apparently doesn't see it. I can't even eject it (Apple lappy, you see... No buttons, just a slit for the bay). Any ideas?!?

| Code: | | dmesg | grep -i dvd |
sth like that
how is it connected?
check /etc/udev/rules.d/70-persistent-cd.rules; it might be safe to delete it (try rename first) so the devicenodes are re-created, reboot&check.
GOOD LUCK!

* dmesg gives nothing
* The DVD bay is inbuilt in the laptop
* I renamed /etc/udev/rules.d/70-persistent-cd.rules to /etc/udev/rules.d/70-persistent-cd.rules.off; after reboot, nothing changed, a new file wasn't created and the DVD device still could not be found.
[EDIT]: The dvd does work under OS X (I have other OSs in this machine), so it isn't likely that it is a hardware or BIOS problem. Everything points to the kernel.

then there's most likely a kernel-option missing; on my amd64-nforce570 box i get
| Code: | x2 ~ # dmesg | grep -i dvd
ata5.00: ATAPI: TSSTcorpCD/DVDW SH-W163A, TS01, max UDMA/33
scsi 4:0:0:0: CD-ROM TSSTcorp CD/DVDW SH-W163A TS01 PQ: 0 ANSI: 5 |
and my kernel options are
| Code: | CONFIG_SCSI=y
CONFIG_SCSI_DMA=y
CONFIG_SCSI_WAIT_SCAN=m
CONFIG_SCSI_SPI_ATTRS=y
CONFIG_ATA=y
CONFIG_ATA_ACPI=y
CONFIG_ATA_SFF=y
CONFIG_SATA_NV=y
CONFIG_PATA_AMD=y |
(these are probably not identical to your system, but you know where to look)

i was thinking more in terms of pata/sata :wink:
maybe there's a hardware failure?
try to boot systemrescuecd www.sysresccd.org and see if the dvd appears then.
GOOD LUCK!

I had a look at the kernel config, and it doesn't seem like something has changed dramatically since 2.6.24... I used the exact same .config file. I would like to check one of the low-level drivers, but you didn't, and other people who have MacBook Pros didn't either... I'm really stuck with that. Yep, 2.6.24 does recognise my Matshita dvd-r device.
[EDIT]: 2.6.24 reports "ATAPI: MATSHITADVD-R UJ-857". It even appears on thunar!

I have the same problem. Have you found any solution?

Is CONFIG_BLK_DEV_IDECD enabled? It is under (at least for 2.6.27)
Device Drivers -> ATA/ATAPI/...
ATAPI seems to match the description of the cdrom under the earlier kernel.
