Re: no cd/dvd devices detected after kernel change
Using 2.6.24-1-686, my two IDE-connected cd/dvd drives are detected as /dev/sr0 and /dev/sr1, symlinked to cdrom0 and cdrom1, and work perfectly. When I boot 2.6.25-2-686-bigmem, no entries for these devices appear in /dev. snip dmesg and lsmod output I'm not sure this is relevant but when I modinfo on ide_cd_mod it shows : filename: /lib/modules/2.6.25-2-686/kernel/drivers/ide/ide-cd_mod.ko license:GPL alias: ide-cd alias: ide:*m-cdrom* description:ATAPI CD-ROM Driver depends:ide-core,cdrom vermagic: 2.6.25-2-686 SMP mod_unload 686 parm: ignore:charp Note the description : *ATAPI* CD-ROM Driver. In the dmesg of your bigmem kernel your drivers seems to be recognize as SATA, not ATAPI. There's nothing about GSA-H55L in your dmesg ? Because on your normal kernel there is the name of the drives, not in the bigmem kernel. Is the lspci output the same for both kernels ? Thomas Preud'homme Thanks for your reply. GSA-H55L doesn't appear in dmesg for the bigmem kernel, nor do any references to DVD drives. Both appear when booting 2.6.4-1-686. Comparing outputs of lspci for the two kernels, there is a difference for the following device: 03:00.0 IDE interface [0101]: Marvell Technology Group Ltd. 8 Subsystem: ASUSTeK Computer Inc. Device [1043:82a2] In the standard issue kernel, lspci reports: Kernel driver in use: pata_marvell Kernel modules: pata_marvell But the bigmem kernel: Kernel driver in use: ahci Kernel modules: ahci, pata_marvell Might this be the issue? I tried adding ahci to /etc/modprobe.d/blacklist and rebooting the bigmem kernel, but the dvd devices are still not detected. -- Joe Hickey -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Did you try to load this module at the end of the boot ? This module isn't necessary to boot thus you can boot correctly so it should be able to be loaded (is that still correct english ???) at any moment. The problem is more that the module isn't being loaded automatically, with the same conf for both kernels. Sorry not being able to help you more and I'm glad you finally manage to make it works with your bigmem kernel. -- Joe Hickey -- Thomas Preud'homme Why Debian : http://www.debian.org/intro/why_debian signature.asc Description: This is a digitally signed message part.
