Guru Meditation / Software Failure CodesFormat of Guru Meditation messages:
| | Subsystem ID | | General Error | | Specific Error | | Address of task |
| 00 | 00 | 0000 | 00000000 |
If the first digit of the subsystem ID is greater than 3, there is no way to recover from the error. In these cases, subtract 8 from the first digit to get the subsystem ID number.

CPU traps or exceptions are defined by the CPU and not the AmigaOS. There are 256 vectors for CPU exceptions: with the lower 64 being hardware defined and the upper 192 being user definable. Specific examples of some that would show up in a Guru meditation error are as follows:
| 2 | Bus Error |
| 3 | Address error |
| 4 | Illegal instruction |
| 5 | Divide-by-zero |
| 6 | CHK instruction |
| 7 | TRAPV instruction |
| 8 | Privilege Colation |
| 9 | Trace |
| 0000000A | OP code 1010 |
| 0000000B | Op code 1111 |
