 |
|
Hello everyone,
yesterday I changed my running kernel from 29-r5 to 30-r1 with genkernel all. Before that I copied the kernel-config-x86-2.6.29-gentoo-r5 from /etc/kernels/ to /etc/kernels/kernel-config-x86-2.6.30-gentoo-r1
Genkernel all passed through clean.
Everything seemed to be running fine until I inserted a dvd into my dvd drive. If I try to mount this dvd I get everytime this:
| Code: |
BUG: unable to handle kernel NULL pointer dereference at 00000024
IP: [<c037d4df>] ide_complete_rq+0xf/0x3b
*pdpt = 000000003682d001*pde = 0000000000000000
Oops: 0000 [#1] SMP
last sysfs file: /sys/block/sda/uevent
Modules linked in: ***

*** obvisiosly every loaded module is here shown, quite a lot, because I am using the live cd's config. additionally: vmci, acpi_cpufreq, nvidia(P)
due to: vmware-modules (server2), NVIDIA 180er driver, svgalib
/dev/hda DVD burner (IDE channel1: master: no problems with both kernels)
/dev/hdb DVD ROM (IDE channel1: slave:causes this error with the 30-r1 but not with 29-r5 and older)
Any Ideas?

| If you have both CONFIG_IDE (the legacy IDE drivers) and CONFIG_ATA (the newer libata drivers) enabled in the same kernel, this can cause problems, because the drivers mostly overlap. |

That's my config since 2.6.29 . Maybe I have to change
| Code: | | CONFIG_IDE_LEGACY=y |
to | Code: | | # CONFIG_IDE_LEGACY is not set |
? |

No, you want | Code: | | # CONFIG_IDE is not set |
which will get rid of the entire IDE section. |

That doesn't work. With this, I got no /dev/hdX dvd device. |

When you switch to the newer libata driver, the devices are now /dev/sdX. So you'll need to modify your /etc/fstab and /boot/grub/grub.conf

Ok, but how and where exactly can I do this?
I deactivated the whole section:
Device Drivers --> ATA/ATAPI/MFM/RLL support
And acitvated (built-in) everythin I found in that section:
Device Drivers --> Serial ATA (prod) and Parallel ATA (experimental) drivers
SCSI Cdrom is also active.
But there were no /dev/sd[b-c] optical devices to mount manually. (sda is my working raid controller raid10 array) |

The 1st cd-rom device should be /dev/sr0. You should also have symlinks /dev/scd0, /dev/cdrom, /dev/cdrw, /dev/dvdrom, and /dev/dvdrw all pointing to sr0. Assuming you have the correct libata PATA driver for your chipset selected in kernel config. You'll need to enable "ATA SFF Support" in "Serial ATA (prod) and Parallel ATA (experimental) drivers", and select the driver (I don't use genkernel so it may be already done).

Thank you, that sr0 was the crucial hint. Now everything works fine again, thanks to all!!! |
