Obsd won't install to acer laptop
After installing successfully to my desktop pc OpenBSD 4.9(i386) i tried to to do the same to my acer laptop.I used the same cd that i used for the desktop yet when i boot from the cd i get "Code dump" ,"Memory dump" and "Stack trace" and does not boot.
I also followed this instructions : http://www.openbsd.org/faq/faq14.html#flashmemLive and when i boot from the usb i get the same error. I have an acer aspire 5520,2GB Ram,amd athlon 64x2 dual core. Any ideas or thoughts on what could be wrong? edit: I also tried the "amd64" version and the same thing happens!The usb has 1gb capacity! Last edited by sepuku; 6th July 2011 at 10:56 PM. |

No better luck with your cd "Basic LiveCD".
I post some info as i see it right now: trap:4(0): protection fault cn_tab=0xfeb5 4 lines under:Core fump [0x44df7] then some hex numbers Then Memory dump and some zeros,then stack trace [0xfe5d] and some more numbers. That's all! |

You might want to run memtest86+ on that system before proceeding further, if things go well.. reproduce with a snapshot.

First: This is great news! Why? It means that whatever the problem is, it is nothing you did.
What else we actually know, so far:
I've not seen your model of laptop mentioned on the misc@ mailing list. I've seen the 5520G, which might be the same, but it was only mentioned in an unrelated bug report for OpenBSD 4.3, not in the mailing list. Don't give up entirely just yet. Here are two things to try, in order:
The serial console discussion in FAQ 4.16 The link to how to report a problem in that FAQ section. Sections b. and c. in my wish list for new users, here:http://www.daemonforums.org/showthread.php?t=596 Please do not submit a bug report using my Live Media, it is not "vanilla" OpenBSD. It uses the GENERIC kernel, but it has a modified /etc/rc subsystem to provide filesystems in RAM for key structures that are normally read/write, including /etc itself. Disabling ACPI on boot. Use the RAMDISK kernel from install media rather than live media. You don't want the latter if APM is not available on that laptop, because it takes a long time to boot and you risk overheating the laptop.

jggimi's contributions are often well crafted and informative, but it seems as if yours have been mostly post_count++;
Not trying to dissuade you from helping others, but if you can't contribute something to a thread it's probably better to not reply.. just saying, feel free to ignore me though.. it's just a friendly observation. |

Hello and thank you for your replies!
If i follow your steps in the ukc prompt,when i press "quit" the system is halted and i have to reboot to continue and then i get the same errors. Then booted the UKC prompt,just typed quit,all devices where read by the system and I managed to see Install,Upgrade,Shell: i installed succesfully and after reboot i got the same error. Then i did the same again:booted the ukc,just typed quit: went to shell but i have no config: "sh: config: not found" :/ I have already looded the BIOS defaults and the hdd is IDE and it's the only option! |

But, config will not help you, since it appears disabling ACPI halts the system. |

You could boot your installed system, with "-c", and quit at the UKC> prompt, and see if normal function is obtained.

Until your problem is resolved, you might experment and see if the -a option and its prompts also works. if that works, you may find you prefer responding with defaults (pressing ENTER twice) easier than typing "quit". And for either amd64 or i386, the boot.conf(5) file can be used to set a boot command with either -c or -a, so you need not type one or the other at the boot> prompt.
