Yesterday I compiled my own kernel, by using the instructions from this howto by falko. The compilation and installation went fine, but for some reason I can't boot into it. It probably has something to do with the fact that my sata disk are seen as scsi disk by linux, because before I get a kernel panic, the kernel is waiting for sda and sda2 (root) to show up. I wish I could post te complete error, but I can't seem to find it in the /var/log files. Ofcourse I already tried google, but there are only a few hits, and they are all about virtualization with Xen. I hope someone can point my in the good direction, because I'm out of ideas. Maybe you'd like some more info about my hardware: I've got only one sata disk that is connected to a motherboard with some RAID functions, but as far as i know it just works as JBOD (Just a Bunch Of Disks). It probably isn't even connected to a RAID supporting connector. Edit: This is my menu.lst : title Debian GNU/Linux, kernel 2.6.20-rc6-default3 root (hd0,2) kernel /vmlinuz-2.6.20-rc6-default3 root=/dev/sda2 ro initrd /initrd.img-2.6.20-rc6-default3 savedefault title Debian GNU/Linux, kernel 2.6.20-rc6-default3 (single-user mode) root (hd0,2) kernel /vmlinuz-2.6.20-rc6-default3 root=/dev/sda2 ro single initrd /intird.img-2.6.20-rc6-default3 savedefault title Debian GNU/Linux, kernel 2.6.18-3-amd64 root (hd0,2) kernel /vmlinuz-2.6.18-3-amd64 root=/dev/sda2 ro initrd /initrd.img-2.6.18-3-amd64 savedefault title Debian GNU/Linux, kernel 2.6.18-3-amd64 (single-user mode) root (hd0,2) kernel /vmlinuz-2.6.18-3-amd64 root=/dev/sda2 ro single initrd /initrd.img-2.6.18-3-amd64 savedefault
I guess some module is missing in your initrd.img-2.6.20-rc6-default3. Did you compile your kernel with SATA support?
Well, I'm not sure, but I think I did. I took the config file from my working stock kernel, And the only thing I changed is adding support for KVM. I'll check for SATA support in the morning. And I'll try google for those modules in initrd. This afternoon I realized that my error is probably simular as the one in your howto. But I'm really sure "Fusion MPT device support" is compiled into my kernel.
config-2.6.20-rc6-default3: # # Fusion MPT device support # CONFIG_FUSION=y CONFIG_FUSION_SPI=m CONFIG_FUSION_FC=m CONFIG_FUSION_SAS=m CONFIG_FUSION_MAX_SGE=40 CONFIG_FUSION_CTL=m CONFIG_FUSION_LAN=m The only match for SATA in this file is: # # Please see Documentation/ide.txt for help/info on IDE drives # # CONFIG_BLK_DEV_IDE_SATA is not set So, I guess I have to recompile my kernel with SATA support?
In the config file for my working stock kernel I also found this line when searching voor SATA: CONFIG_SCSI_SATA=m CONFIG_SCSI_SATA_AHCI=m CONFIG_SCSI_SATA_SVW=m CONFIG_SCSI_ATA_PIIX=m CONFIG_SCSI_SATA_MV=m CONFIG_SCSI_SATA_NV=m CONFIG_SCSI_PDC_ADMA=m CONFIG_SCSI_HPTIOP=m CONFIG_SCSI_SATA_QSTOR=m CONFIG_SCSI_SATA_PROMISE=m CONFIG_SCSI_SATA_SX4=m CONFIG_SCSI_SATA_SIL=m CONFIG_SCSI_SATA_SIL24=m CONFIG_SCSI_SATA_SIS=m CONFIG_SCSI_SATA_ULI=m CONFIG_SCSI_SATA_VIA=m CONFIG_SCSI_SATA_VITESSE=m I guess this is why my kernel isn't working, but why wasn't it enabled when I compiled it? I know for sure that I loaded this config file in menuconfig.
I had the same problem, when I compiled kernels with Debian stock configuration. The problem waas solved, when I compiled with command: Code: make-kpkg --initrd kernel_image in kernel source root directory, and installed with command: Code: dpkg -i linux-image-2.6.20-10.0.Custom-amd64.deb (I compiled on amd64 system.)
