| | 23 | ================== |
|---|
| | 24 | |
|---|
| | 25 | Module cdrom.o in all 2.2 kernels conflicts with our sensors.o module. |
|---|
| | 26 | You can get an Oops if cdrom.o is unloaded after sensors.o was loaded. |
|---|
| | 27 | Below is a small diff that you can apply to the kernel to correct this. |
|---|
| | 28 | Another solution is to make sure cdrom.o is never unloaded, or to make |
|---|
| | 29 | sure it is not a module but compiled into the kernel proper. |
|---|
| | 30 | |
|---|
| | 31 | The diff corrects a long-standing /proc bug. It will go into kernel 2.2.2 |
|---|
| | 32 | or later in a somewhat modified form. It was written by Jens Axboe |
|---|
| | 33 | <axboe@image.dk>. |

| | 57 | Kernel i2c conflict |
|---|
| | 58 | =================== |
|---|
| | 59 | |
|---|
| | 60 | An older version of the i2c modules is distributed in 2.2 and late 2.1 |
|---|
| | 61 | kernels. If you try to use it at the same moment as our i2c modules, you |
|---|
| | 62 | may get into trouble. There is no nice solution for this yet. |
