No go, same error. I think we'll need more information on how your system is set up to boot: First, it's not my system, it's my installer. I'm taking on the task of creating a dual-installer (pictures linked-to below): http://www.twitpic.com/89l2ub/full http://www.twitpic.com/89l4n6/full I usually use kgzip'd kernels on my installer. It's always worked in the past (period). The reason for doing so is that it takes a 14MB GENERIC kernel and reduces it to 4.6MB (pretty obvious incentive there). partition layout, None to speak of. All I'm really doing to replicate the BTX halt is loading up an ISO with the following contents: 1. loader(8) from unmodified RELENG_9 2. kgzip(1)'d kernel -- again, unmodified RELENG_9 (GENERIC) 3. load kernel with FICL ``load'' 4. boot 5. BTX halted immediately what boot blocks and loaders are in use, etc. All from 9.0-RELEASE How are you instructing it to load that particular kernel, for example? Here's the FICL syntax used which replicates the BTX halt: load /kernels/GENERIC-i386-9.0.kgz load -t mfs_root /boot/fis_mfsroot9.gz set vfs.root.mountfrom=ufs:/dev/md0 set vfs.root.mountfrom.options=rw boot This leads to BTX halt.

kgzip(8) regression in RELENG_9 GENERIC
Taking a GENERIC 9.0-RELEASE kernel and running kgzip(8) on it produces an unusable kernel which causes immediate BTX halt in loader(8). NOTE: This is w.r.t. a completely un-modified src-tree (including the GENERIC config itself). Just thought I'd share this regression. 8.1-RELEASE-p6 doesn't have this problem. To replicate (warning DO NOT DO THIS unless you know how to recover the boot process using either interactive loader(8) or LiveCD): 1. Install i386 9.0-RELEASE and make sure you select that you wish to unpack src.txz 2. Go to /usr/src/sys/i386/compile and say: config -C -g GENERIC 3. Go to ../compile/GENERIC and say: make cleandepend make depend make 4. Say: kgzip kernel 5. Copy kernel.kgz to /boot 6. Add kernel=kernel.kgz to loader.conf(5) 7. Reboot 8. Witness your own death via BTX halted -- Devin NOTE: Looking for confirmation from at least one other individual before filing a PR on this one. It could be any number of factors and not a true regression. For example, I'm using VMware Workstation 7.1 to replicate this. _ The information contained in this message is proprietary and/or confidential.
