Hi Dave,

kmalloc is returning 0 when I try to allocate 24335 bytes inside a FEC

kernel feature "[*] Allow allocating large blocks (> 1MB) of memory" to
see if this fixes my problem, but no joy.
Does anyone have an idea of what I can do to get past this?
Can you show the code?

Here is a snippet of my kernel output when loading:

ttyS1 at MMIO 0x10008700 (irq = 100) is a ColdFire UART
ttyS2 at MMIO 0x10008800 (irq = 101) is a ColdFire UART
