When running the following occurs: ack:~/linux-2.6.32# scripts/kconfig/streamline_config.pl >config_strip using config: '.config' Use of uninitialized value $ksource in concatenation (.) or string at scripts/kconfig/streamline_config.pl line 117. dock config not found!! module pata_sis did not have configs CONFIG_PATA_SIS As a result: it couldnt map one currently loaded module properly and the other module had been properly mapped, but somehow the dependency/integrity check triggered it, since it wasnt enabled properly. I checked the output of the script and yea as I assumed CONFIG_ACPI_DOCK is not set. 'dock' refers to: ack:~/linux-2.6.32# modinfo dock filename: /lib/modules/2.6.26-2-amd64/kernel/drivers/acpi/dock.ko and the belonging Kconfig file says: config ACPI_DOCK bool "Dock" depends on EXPERIMENTAL help This driver supports ACPI-controlled docking stations and removable drive bays such as the IBM Ultrabay and the Dell Module Bay. The same with 'pata_sis' (CONFIG_PATA_SIS is also not set) .. ack:~/linux-2.6.32# modinfo pata_sis filename: /lib/modules/2.6.26-2-amd64/kernel/drivers/ata/pata_sis.ko and the belonging Kconfig file: config SATA_SIS tristate "SiS 964/965/966/180 SATA support" depends on PCI select PATA_SIS help This option enables support for SiS Serial ATA on SiS 964/965/966/180 and Parallel ATA on SiS 180. The PATA support for SiS 180 requires additionally to enable the PATA_SIS driver in the config. If unsure, say N. In the end (if one ignored the two missing modules) a make silentoldconfig didnt even work. What I did to reproduce this was using the standard kernel config of debian lenny's amd64 branch. PS: I wrote such software myself, but I am going a totally different approach. Your idea is not that bad actually (I am enabling kernel config options and I am tracking all dependencies properly, while you can just ignore them, since your script only disables stuff). regards, Patrick
