Unfortunately it is needed. It is embedded system, where bootloader
always tries to boot from the first device (dvd-rom). Second device
(hard disk) is not yet ready when kernel is loaded from flash and does
probe.
Can you show us the dmesg (printk) output from libata, _without_
dev_select or other "wait for drive to settle" special code?
Turn on ATA_DEBUG and ATA_VERBOSE_DEBUG in include/linux/libata.h before
generating this output, please.
Thanks,
Jeff
