Maybe a bit off topic but it depends on EXPERIMENTAL so why the the menu is not telling this ? and why the default is 'y' for it ? IMO everything depends on EXPERIMENTAL should 1) Tell it is EXPERIMENTAL ( visible to the user in menu ) " Foo New stuff ( EXPERIMENTAL ) " 2) Should not default to 'y' , is up to the users/admins to set EXPERIMENTAL things to Y/M , isn't it ?

Can you check the major number of your /dev/sdc? I've seen that
/dev/sd* is linked to bsg devices somehow.

All my disks are doing this sdc was meant as example.
...
$ ls -la /dev/sd{a,b,c}
brw-r- 1 root disk 8, 0 16. Jul 23:11 /dev/sda
brw-rw 1 root disk 8, 16 16. Jul 23:11 /dev/sdb
brw-r- 1 root disk 8, 32 16. Jul 23:11 /dev/sdc
...
sd{a,b} are SCSI disks and sdc is an ATA disk.
You can get the used config from there :

I've not tested this yet (need to find sata drives in my workplace),
but James Bottomley told me that both works for him with bsg enabled.
It might worth trying the latest git tree.

It certainly does work for me. However, my ATA devices are connected to
an aic94xx SAS controller. Although this uses libata, the ioctl path is
probably slightly different from the libata one. I assume you're using a
SATA controller? Unfortunately I have no ability to test on a SATA
controller, but I'd suggest looking at the ioctl and REQ_BLOCK_PC paths
in libata for clues.

No is not an SATA controller.
sda and sdb are SCSI disks connected to an Adaptec AIC-7892P U160/m
controller using the aic7xxx driver.
sdc is an ATA-7 disk connected to an IDE controller ( 82801BA IDE U100
) using libata and the ata_piix driver.

OK, this definitely works for me, that's what my root disk is on. I
think this isn't a kernel problem ... I think it's a udev name clash
problem. Try the attached patch, which corrects the names:
