I can crash khttpd at will on a totally vanilla linuxppc_2_4_devel kernel as of changeset 1.749 using an open source load generator, with or without the patch that fixes a khttpd crash on x86 ( http://www.kegel.com/linux/khttpd/khttpd-unbork.patch ).
This crash is not present on the imac with current kernels, nor in Hard Hat 2.0 on this same board, nor on the PC with current kernels. I believe it's a bug in the linuxppc_2_4_devel trunk. Now that I've got it happening with 1.749, I'll try earlier versions in hopes I find an older version that doesn't oops, and narrow down the cause.
