libata update?

libata update?

[Erik Ohrnberger]

It's been a number of months since I build a custom kernel with the libata
incorporated to deal with multiple Promise EIDE controller card's 'DMA
Expiry' errors.

I'd like to re-build basically the same thing with an updated kernel and
updates libata.  Could someone point me into the right direction to achieve
this?

Thanks in advance
Erik.

All of the PATA stuff was merged in 2.6.19, if you want the very latest 
and greatest you can try the -mm tree..

Not to sound too dense or anything, but is there a HOWTO for this kernel to
enable the libata code?  

I've read through the Documentation/kernel-parameters.txt file, and seems
like all I have to do is include libata.atapi_enabled=1 combined_mode=libata
on the grub.conf line to enable it, but when I boot that kernel with that
option, I get an error message: 'Block device /dev/sda1 is not a valid root
device' and a 'boot() ::' prompt.

Thanks in advance,
	Erik.

You shouldn't need atapi_enabled=1 anymore, and combined_mode only 
applies if you're using an Intel controller with that 
combined/legacy/AHCI selection braindamage. Did you select the right 
driver options in the kernel configuration? You'll either have to 
compile the driver(s) into the kernel or potentially do some 
distro-specific magic to ensure the modules get loaded in the initrd.
