The problem I have with this kernel is that floating point emulated instructions which perform stores seem to be falling over. There is a bug in the fault handling code for stock 2.4.21 that I am using it would seem but am looking at whether it is worth fixing it. By all accounts I might as well just use the floating point emulation in libc but am still interested in enlightened feedback. Cheers, Jon. ** Sent via the linuxppc-embedded mail list.
