Hi, I have a SGI Octane IP30 and was able to boot Linux on it with the ip30-r10k+-20050128.img Gentoo kernel. Nevertheless I noticed that this kernel is very unstable. Once I was lucky and able to bootstrap Debian before the kernel paniced again (usually a "unaligned instruction access in arch/mips/kernel/unaligned.c::do_ade, line 544[#3]"). I tried to compile a newer 2.6.19-rc1 kernel and applied the two IOC3 and IP30 patches from ftp://ftp.linux-mips.org/pub/linux/mips/people/skylark/. First of all the patch fails slightly and needs manual adjustments. Compiling results in an error, do_IRQ() is called with only one parameter instead of two. So I wonder what kernels are compatible with linux-mips-2.6.19-rc1-ip30-r28.patch.bz2. Do I need other patches as well? Also the kernel config file skylark-approved-config-tm in skylark/ is out of date. It seems to match a 2.6.12 or similar version. PS: Please CC: me. Jens
