I need to get an initial ramdisk working in a recent 2.3.5x or later
kernel, but they're borken. :) I don't know when the bug first appeared.
In rd.c (rd_open), the following code causes an oops and hangs the boot:
/*
* Immunize device against invalidate_buffers() and prune_icache().
*/
if (rd_inode[DEVICE_NR(inode->i_rdev)] == NULL) {
if((rd_inode[DEVICE_NR(inode->i_rdev)] = igrab(inode)) != NULL)
atomic_inc(&rd_inode[DEVICE_NR(inode->i_rdev)]->i_bdev->bd_openers);
}
In the third line, i_bdev is null. Commenting out the code does not fix
the problem. (Instead I get a kernel panic that VFS cannot mount root
on 01:00.) The kernel never seems to identify that an initrd exists in
the first place. I'm using GRUB 0.5.94 to load a cramdisk. It works
fine with 2.2.14. At the very least, 2.3.51 and onward are broken.
Thanks for any help!
Regards,
Jeff
