I'd suggest to drop this patch, and I'll stop testing IP checksum > generation for mps2-an385:mps2_defconfig. I'm trying to run an ARM kernel built with GCC 13.2 and mps2_defconfig on the mps2-an385 qemu emulation, and I get the following fatal error. $ qemu-system-arm -M mps2-an385 -kernel vmlinux qemu: fatal: Lockup: can't escalate 3 to HardFault (current priority -1) R00=00000000 R01=00000000 R02=00000000 R03=00000000 R04=00000000 R05=00000000 R06=00000000 R07=00000000 R08=00000000 R09=00000000 R10=00000000 R11=00000000 R12=00000000 R13=ffffffe0 R14=fffffff9 R15=00000000 XPSR=40000003 -Z-- A handler FPSCR: 00000000 Abandon (core dumped) Can you tell how to proceed ?
