| 1202 | Some pieces of the kernel contain a lot of flow changes which can |
| 1203 | quickly fill up the hardware trace buffer. When debugging crashes, |

| 1205 | space when in reality an application is buggy. |

| 1214 | This option enables special console drivers which allow the kernel |
| 1215 | to print messages very early in the bootup process. |
| 1216 | |
| 1217 | This is useful for kernel debugging when your machine crashes very |
| 1218 | early before the console code is initialized. After enabling this |
| 1219 | feature, you must add "earlyprintk=serial,uart0,57600" to the |
| 1220 | command line (bootargs). It is safe to say Y here in all cases, as |
| 1221 | all of this lives in the init section and is thrown away after the |
| 1222 | kernel boots completely. |
