I had to recompile my kernel to add module unloading (which I didn't bother with on the last one) because I am learning to write device drivers and of course need to repeatedly load and unload test modules. So I checked www.kernel.org
, noticed there was a new one and decided to use that.
I use an initrd and unfortunately I repeatedly get a "can't mount /dev/sysroot ... no such file", which is something I would expect if support for the hard-drive has been left out accidentally. I diff'd my .configs (the last one was from 184.108.40.206) and noticed that BLK_DEV_SCSI is no longer an option -- which formerly it was required for a SATA HD.
[later] hey stooopid me! (I did have the specific SATA driver turned off)
