yop, that was it |

|
| 54 |
though you wrote about /dev/hda*, which means you should be a bit more |
| 55 |
carefull if you used the IDE drivers (under ATA/ATAPI/.... support, |
| 56 |
thats the "CONFIG_IDE" option) and disabled the CONFIG_IDE options, you |
| 57 |
have to enable it under |
| 58 |
Serial ATA (prod) and Parallel ATA (experimental) drivers (CONFIG_ATA) |
| 59 |
and also your device might get renamed to sd* instead of hd* (I don't |
| 60 |
know, I have only a cdrom, that becomes sr0 ;) |
| 61 |
|
| 62 |
But I think that the real problem was with those SYSFS_DEPRECATED |
| 63 |
options, so you might be able to get things working with just disabling |
| 64 |
those and leaving IDE as it was... |
