2.5.46 won't boot with root=/dev/hda5, does with /dev/ide.../part5

[Peter T. Breuer]

2.5.44 booted fine with root=/dev/hda5 on my laptop (one ide disk, all
ext2).

2.5.46 stopped at VFS cannot blah blah "hda5", after reading the
partition table fine.

I got 2.5.47 to boot (gave up on 2.5.46) by using the
root=/dev/ide/../part5 param instead.

Yes, it took me a week to think of that.

There was no change between configs except what make oldconfig
threw up to make a decision on (and I always say no).

Choice selections from config ..

  ...
  # CONFIG_HPFS_FS is not set
  CONFIG_PROC_FS=y
  CONFIG_DEVFS_FS=y
  # CONFIG_DEVFS_MOUNT is not set
  # CONFIG_DEVFS_DEBUG is not set
  CONFIG_DEVPTS_FS=y
  # CONFIG_QNX4FS_FS is not set
  CONFIG_ROMFS_FS=m
  CONFIG_EXT2_FS=y
  CONFIG_EXT2_FS_XATTR=y
  # CONFIG_EXT2_FS_POSIX_ACL is not set
  CONFIG_SYSV_FS=m
