2.5.60 "Badness in kobject_register at lib/kobject.c:152"

[Guennadi Liakhovetski]

Hell

I reported earlier a problem with getting 2 flash disks to work in
true-IDE mode with 2.4.[18|20]
(http://www.uwsg.indiana.edu/hypermail/linux/kernel/0302.0/0918.html).
Today I tried 2.5.60. Tried with 2 flash-disks and with 1 only. With 2
flash-disks connected the kernel panics (notice, hda disappears after the
initial detection):

...

Kernel command line: BOOT_IMAGE=4 ro root=301 hdb=flash console=ttyS0,38400 console=tty1
ide_setup: hdb=flash

With only one (hda) disk the system boots, but there's still an error
