Ubuntu Hardy heron on a Sony Vaio VGN-C2S_L

I bought this laptop about a month ago. The series was reaching the end of life, new models coming in, I got it for a very low price. My previous laptop was dying and I was looking for a smaller machine (this one is 13″3). Searching the internets did not show issues with Ubuntu, intel video, wireless and sound cards, so I spent the money.

  • Only after starting the hardy Live CD did I stumble upon this bug. No boot at all, with this message:
    ACPI: EC: acpi_ec_wait timeout, status=0, expect_event=1
    ACPI: EC: read timeout, command=128

    The workaround is to boot the laptop on battery or disable the “quiet” argument to the kernel. The power cord can be plugged in after login into the session.

  • CPU: Intel Core2 CPU T5500 @ 1.66GHz
  • Video: Intel Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller, working out of the box, compiz enabled
  • Network: Marvel 88E8036 PCI-E Fast Ethernet Controller + Intel PRO/Wireless 3945ABG Network Connection, working out of the box
  • sound: Intel 82801G (ICH7 Family) High Definition Audio Controller, working out of the box
  • Not tested: Bluetooth, 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD)
  • No proprietary driver required
  • Moving this laptop from one location to the other, with very different networks, is finally easy

Except the boot bug, which can be a stopper to many users, 2.6.24-19-generic runs fine.
All in all, I’m happy :)

Edit: the boot bug is now solved in Ubuntu Hardy.

    I’ve the same problem (ACPI error) on Vaio FE41E and Ubuntu.
    Now with the new kernel version 2.6.24-20 it works very fine, no more acpi problem on boot! :)
