When I upgraded to Rawhide, netboot no longer worked and the kernel gets stuck
in an endless loop, stating "__find_get_block_slow() failed" and completely
It did however state that the block size was 4096 bytes. Since initrd usually
uses 1024 bytes, I tried adding ramdisk_blocksize=1024 to the kernel parameters.
An behold, it started to work.
I leave it to you to figure out why and do the necessary tweaks. ;)
