But I'm building using "stable" gcc (gcc version 3.3.5 (Debian 1:3.3.5-13)). I also have enabled SMP and DEBUG_SLAB in my kernel builds. Diff between c3000_config and my mine is appended (It's short). Kernel should warn about, but handle data alignment exceptions. So this sounds like two bugs: one for the misaligned data and another that the kernel isn't handling it properly. I expect this is another exposure that gcc 3.x was hiding by automatically aligning some data types. > There's also some undefined symbols in a module. Ok - those should be easy to sort out. I'll look at that tonight. I haven't noticed it on my builds. thanks, grant grundler <505>diff /boot/config-2.6.14-rc2-pa6 arch/parisc/configs/c3000_defconfig 3,4c3,4 < # Linux kernel version: 2.6.14-rc2-pa5 < # Mon Oct 17 19:39:53 2005 --- > # Linux kernel version: 2.6.14-rc2-pa1 > # Sat Sep 24 18:33:00 2005 22d21 < CONFIG_LOCK_KERNEL=y 40d38 < # CONFIG_CPUSETS is not set 70d67 < CONFIG_STOP_MACHINE=y 83,84c80 < CONFIG_SMP=y < CONFIG_HOTPLUG_CPU=y --- > # CONFIG_SMP is not set 98d93 < CONFIG_NR_CPUS=4 916a912,913 > CONFIG_SND_AD1889=y > # CONFIG_SND_AD1889_OPL3 is not set 939,940d935 < CONFIG_SND_AD1889=y < # CONFIG_SND_AD1889_OPL3 is not set 1280c1275 < CONFIG_DEBUG_SLAB=y --- > # CONFIG_DEBUG_SLAB is not set 1287d1281 < # CONFIG_DEBUG_RWLOCK is not set grundler <506> _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
