I got the following from a 2.5.7 machine.

hdc: ide_set_handler: handler not null; old=c01e5af0, new=c01e5af0
bug: kernel timer added twice at c01e6925.
hdc: ide_set_handler: handler not null; old=c01e5af0, new=c01e5af0
bug: kernel timer added twice at c01e6925.

The first two occured at about the same time. The second two occured the
next day. HDC is a WDC WD307AA ATA drive. The controller is a PIIX4 (82371AB)
using DMA (UDMA33).

The relevant section of the system map is :

c01e52c0 T do_rw_taskfile
c01e5450 T do_taskfile
c01e55b0 T set_multmode_intr
c01e5610 T set_geometry_intr
c01e5670 T recal_intr
c01e56b0 T task_no_data_intr
c01e5720 t task_in_intr
c01e5840 t pre_task_out_intr
c01e5940 t task_out_intr
c01e5a90 t pre_bio_out_intr
c01e5af0 t bio_mulout_intr
c01e5ce0 t task_mulin_intr
c01e5e70 T ide_cmd_type_parser
c01e5ff0 t ide_init_drive_taskfile
c01e6010 T ide_wait_taskfile
c01e6120 T ide_raw_taskfile
c01e6180 t ide_wait_cmd
c01e6210 T ide_cmd_ioctl
c01e6420 T ide_task_ioctl
c01e64e0 t init_hwif_data
c01e66a0 T drive_is_flashcard
c01e67d0 T __ide_end_request
c01e68c0 T ide_set_handler
c01e6940 t ata_pre_reset
c01e6a00 T ata_capacity
c01e6a40 t ata_special

This looks harmless, like something was set twice.
