Felipe, I've spent about an hour examining the log-files and reports. Everything points to a (intermittent) hardware problem. I'm inclined to think it could be something causing a memory-mapping issue right now, but that is just a guess with no evidence to point to.
Here's some things you can do to try and narrow the cause down in order of difficulty: 1. Don't use the VESA framebuffer device - I think it is a module in Hardy so you may have to remove it from the initial ram-disk as well as removing "vga=0x031b" from the kernel command-line at boot-time. 2. Add " debug" to the kernel command-line to capture more detail about the boot process in /var/log/kern.log 3. Reset BIOS to factory defaults. 4. Remove each memory module, give the contacts a wipe with rubbing alcohol or fine wet'n'dry paper and replace them firmly 5. Strip the system down to the barest possible hardware and use a live- CD. (remove additional video adaptors, non-critical PCI adapters, hard disks, etc). 6. If (5) results in a stable system that doesn't exhibit the problem, add devices back in one-by-one and boot from the live-CD after each addition. If the problem recurs after such a step you've pin-pointed the cause and proceed to figuring out a solution. -- BUG: unable to handle kernel paging request https://bugs.launchpad.net/bugs/325238 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
