Hi, has anybody seen the same? I'd like to include the serial.o module into recent kernels (2.3.x). No luck, I always get a machine check. I'm not sure where it is. This happens up to 2.3.50-pre2. I suppose it has to do with the SHARE_IRQ etc. Any ideas? Thanks Andreas ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
