run "make menuconfig" in your new kernel dir. |

|

check to ensure ext3 is compiled in. (not sure why it wouldn't be) |

11 |
check to make sure you've got udev or devfs installed properly in both |
12 |
kernels (maybe one isn't defined in the kernel, and the old kernel had |
13 |
it). I'd really try to ensure you're running udev and not devfs, but |
14 |
first things first. |

IF SATA: |
17 |
Make sure the proper SATA options are the same for each kernel. There's |
18 |
one SATA option that isn't compatible with another SATA option. (it |
19 |
could be fixed in newer kernels by now) |

|
21 |
IF SCSI: |
22 |
Make sure all your SCSI options are the same for each kernel. |
23 |
|
24 |
also you can compare the two configs of each kernel. |
25 |
|
26 |
Compare Option #1: |
27 |
|
28 |
# diff -u kernel-old/.config kernel-new/.config |
29 |
|
30 |
Compare Option #2: |
31 |
|
32 |
# vimdiff kernel-old/.config kernel-new/.config |
33 |
|
34 |
|
35 |
You can also pipe #1 through less (or more). |
