I just tried the new (second 2.05R) boot.flp, and it still panics with the same message on bootup after the PCI probe is completed. panic: cannot mount root syncing disks... done Automatic reboot in 15 seconds - press a key on the console to abort I didn't get any replies on the first post, so here it is again. Any help would be greatly appreciated. ---------- Forwarded message ---------- Date: Sun, 11 Jun 1995 02:51:49 -0700 (PDT) From: Howard Lew <hlew@cycle.Stanford.EDU> To: bugs@freebsd.org Subject: 2.05 Release I just ftped the 2.05 release and tried the install, and the installation process went well. But when I rebooted, the system would not boot up. Here's the system I tested it on: 386DX-40, 387 Cyrix MPU, 8MB RAM, 850MB (wd0) with Ontrack DM, and 540MB (wd1). The 850MB has DOS with dynamic drive overlay from Ontrack DM. I was planning on installing 2.05R on the 540MB Conner (entire disk). So after reset, it tries to boot up. I see the usual Ontrack DM overlay stuff, and then it says to press space for floppy boot. It never asks for F1-Disk 1 or F5-Disk 2. (Hmmm... This is strange because the SNAP releases didn't seem to have this boot selection problem. That boot manager seemed to always work fine). If I insert my 2.05 boot.flp disk, and enter hd(1,a)/kernel, it starts booting from wd1. And everything looks good until it finishes probing npx (no immediate problem after the probe). Then it tries probing the PCI stuff. (Yes it really probes for PCI stuff on my 386), and after it finishes the probe, it says: panic: cannot mount root syncing disks... done Automatic reboot in 15 seconds - press a key on the console to abort ----------------------------------------------------------- I redid the installation several times, and here are some additional observations: * If disabled the cache on my 386 motherboard and also disabled the 387, the system no longer probes for the PCI stuff... But then panics with the same message after the NPX probe. * The system panics regardless of whether or not I disable the NPX probe. * I tried disabling practically all the devices except the floppy drive, hard drives, lpt0, and sio1 with no effect -- still panics. * If I go through the installation program and finish the installation, I can use ALT-F4 to see everything on my wd1 drive. There appears to be no problems mounting partions from wd1, but it just can't do it from the hard disk kernel. * The boot.flp kernel does not seem to panic (but then again it is mounting root from mfs). * If I use Ontrack DM 6.03a and set the DOS partition active (I don't know why it became inactive), the system prompts for F1-Disk 1 and F5-Disk 2. But at that prompt, if I choose F1, I get DOS. And if I choose F5, I also get DOS (so they are still booting from wd0 which is my DOS drive). * In the installation... If I choose wd1 and do the partition, and then do the disklabel to mount the partitions, I never see the R flag as mentioned in the help info for Partitions. The CA>= flags do appear, but I never see the R flag appear. Could this be the cause of the problems? * The time zone setting doesn't seem to work (maybe old news sorry). Well, sorry this is kind of out of order. Any help is greatly appreciated. I really would like to get this 2.05R system humming... Thanks in advance for any help. --------------- Some good stuff I noticed fixed: * Help info is there * Many install bugs gone * PPP over a 115200 serial cable link never hangs anymore * no errors in bin extractions
