^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) The 2.4 kernel changed the kernel start address from 0x310000
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) to 0x810000 to make room for the Wildfire's larger SRM console.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) If you're using aboot 0.7 or later, the bootloader will examine the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) ELF headers to determine where to transfer control. Unfortunately,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) most older bootloaders -- APB or MILO -- hardcoded the kernel start
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) address rather than examining the ELF headers, and the result is a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) hard lockup.
