Is there a PS/2 keyboard hooked up to this machine when you're attempting to get serial console output? If so, I'm not too surprised it doesn't work (re: -P flag). Can you try the following? 1) Removing kernel_options and console from loader.conf 2) Place "-P" in /boot.config instead If this doesn't change the behaviour, please replace -P and with -D -h and see if there's any improvement. -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

VBox 3.2.8 & SATA virtual disks & FreeBSD 8.1-STABLE 20100912 -- (virtual) harddisks are not found on boot...
Hello, Freebsd-stable. I have VirtualBox-based FreeBSD 8.1 installation (32 bit, VirtualBox 3.2.8, WinXP/x64 host, but I thinks that host config is irrelevant). Two virtual HDDs are atteched to virtual SATA adapter (channels 0 & 1) and CD/DVD attached to virtual IDE adapter (Primary master). I've used FreeBSD 8.1-STABLE builded about two months ago and everything worked Ok with "Standard" (not AHCI) driver, root FS is ad4s1a. I'veupdatedFreeBSDtoday (12/09/2010) with csup & buildworld/buildkernel/installworld/installkernel (GENERIC kernel). Nothing was changed in VM config/setup. Now it can not be booted because KERNEL doesn't see any HDDs and can not mount root FS. It shows only "acd0" as "GEOM managed disk device". bootloader sees disk and reads kernel & modules without problems. I've tried to "load ahci" on boot prompt, but result is almost the same. AHCI driver sees two channels, but got timeouts on both -- oops, can not mout root FS again. I've tried to load "vboxdrv" (it is build right after kernel & world, so it should be in-sync), but here is abother fault: kernel panics in "(swapper)" process right after "acd0" detection (wihtout vboxdrv kernel complains about missing root FS exactly at same moment). I've googled this problem, but without any success. What should I do to revive my VM? -- // Black Lion AKA Lev Serebryakov ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Serial console problems with stable/8
Hi, On Friday I have updated a machine from 7.1 to stable/8. It is connected to a serial console. With 7.1 everything worked fine, but with stable/8 things seem to break. When the machine boots, everything appears normal, i.e. I get all of the boot output, but then the console freezes. The last thing that appears on the console is the time stamp from the date(1) command at the very end of /etc/rc. I do not get a login prompt, even though I see a getty process on ttyu0. No further output to the console happens, commands like "echo foo > /dev/console" freeze, too. According to ps -alx they hang in "ttydcd". I cannot even su(1) to root because it tries to print a message to the console, so it hangs, too. For the same reason I can't use shutdown(8) either. :-( This is what a hanging su(1) command looks like in ps -alxww: UID PID PPID CPU PRI NI VSZ RSS MWCHAN STAT TT TIME COMMAND 0 1533 1532 0 76 0 3392 3180 ttydcd I+ 00:00.05 su (zsh) Interestingly, the KDB sequences CR ~ ^B/^P/^R/ do work, which use the "low-level" console. So only the "high-level" console is frozen. When I boot with the getty on ttyu0 switched off in /etc/ttys, the console does *not* freeze, and output to /dev/console works normal (I don't get a login prompt, of course). I can use su(1), shutdown(8) and so on. But as soon as I try to start a getty on ttyu0, the darn thing ceases to work. Here's my setup (which worked perfectly fine with 7.1): /boot.config: -P /boot/loader.conf: kernel_options="-P" console="comconsole" /etc/ttys: ttyu0 "/usr/libexec/getty std.9600" vt100 off secure /boot/device.hints: hint.uart.0.at="isa" hint.uart.0.port="0x3F8" hint.uart.0.flags="0x10" hint.uart.0.irq="4" /var/run/dmesg.boot: uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 uart0: [FILTER] uart0: console (9600,n,8,1) The serial port is connected to another PC that runs tip(1) in a screen(1) session, using a 9-pin nullmodem cable. That setup hasn't changed in ages; that other PC is running an older version of FreeBSD. I need this issue to be resolved, because the serial console is required for remote management (the machine is a 3-hours ride away from home). If it can't be resolved, I will have to downgrade it to 7.x. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
