BAN USERThere is no multi processing at boot time, so technically there is only one task running at boot time, it's call the kernel thread; the very first process created comes after the kernel has been decompressed and running, this user space process is called init (PID 1)

A bus is a communication unit that allows the CPU to interact with peripherals, there are different type of buses such as PCI, I2C, MDIO, Memory Buses, etc. Normally each bus would have its own protocol for transmitting data across devices, for example in the case of PCI you can have timeout errors or windows errors (data is directed to unknown addresses/devices). In memory, bus errors would refer to alignment but other errors could be attributed to physical HW problems such as faulty connections. Other type of bus errors could be single and multiple bit errors, this could be addressed by using ECC memory.

According to the "man kill" SIGABRT also generates a core dump, probably it also adheres to the ulimit rules.
