No joy. 2.6.13-rc5 vanilla + this patch still hangs my laptop during boot. So far only the CARDBUS_IO_SIZE reduction patch avoids the hang during boot regression 2.6.13-rc2 introduced. I can send lspci & /proc/ioports if you think that might help. /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
