I searched the mailing list archives and didn't find anything that looks like this, so maybe it's just me, but adding ppbus and lpt0 to my kernel config (sources cvsupped on 4/17) causes my machine to hang hard during boot. The freeze occurs shortly after probing my network card and is accompanied (sometimes) with an error like RTC BIOS diagnostic error ff<clock_battery,ROM_cksum,config_unit,memory_size,fixed_disk,invalid_time> My config looks like (if I comment out the ppc,ppbus, and lpt lines, the kernel works fine): machine "i386" cpu "I586_CPU" cpu "I686_CPU" ident GENERIC maxusers 64 #makeoptions DEBUG="-g" #Build kernel with gdb(1) debug symbols options MATH_EMULATE #Support for x87 emulation options INET #InterNETworking options FFS #Berkeley Fast Filesystem options FFS_ROOT #FFS usable as root device [keep this!] options MFS #Memory Filesystem options MFS_ROOT #MFS usable as root device, "MFS" req'ed #options NFS #Network Filesystem #options NFS_ROOT #NFS usable as root device, "NFS " req'ed options MSDOSFS #MSDOS Filesystem options "CD9660" #ISO 9660 Filesystem options "CD9660_ROOT" #CD-ROM usable as root.
