I'm definitely using insmod and not modprobe to load these modules from initramfs. This is the snippet of ash script which does the loading:
MOD_DIR=/lib/modules/2.6.21.1
insmod ${MOD_DIR}/scsi_mod.ko
insmod ${MOD_DIR}/sd_mod.ko
insmod ${MOD_DIR}/libata.ko
insmod ${MOD_DIR}/ahci.ko
insmod ${MOD_DIR}/ide-core.ko
insmod ${MOD_DIR}/ehci-hcd.ko
insmod ${MOD_DIR}/uhci-hcd.ko
insmod ${MOD_DIR}/usb-storage.ko
insmod ${MOD_DIR}/via82cxxx.ko
insmod ${MOD_DIR}/ide-generic.ko
insmod ${MOD_DIR}/ide-disk.ko
insmod ${MOD_DIR}/mbcache.ko
insmod ${MOD_DIR}/jbd.ko
insmod ${MOD_DIR}/ext2.ko
insmod ${MOD_DIR}/ext3.ko
insmod ${MOD_DIR}/edd.ko
The exact error message I am getting on the target when it tries to load the
first module is:
insmod: module '/lib/modules/2.6.21.1/scsi_mod.ko' not found
It's going to take me some time to incorporate the strace utility into my
app so that we can see what's happening at the system level. I'll report
that a bit later. For now, please find my busybox config attached.
Thanks for the help!
