[Bug 999462] Re: ExpressCard34 slot not hotplugable after boot

 

I have to retract my statement. I'm using a Lenovo x220. 
Disabling "PCI Express Power management" (Config -> Power) via Bios resolves the issue for me. Before Ubuntu became unresponsive (like the card is throwing a lot of interrupts) after the *2nd* hot-plug, first one seems fine though. On AC or Battery did not change the behavior.

Also I noticed "ACPI FADT declares the system doesn't support PCIe ASPM"
in dmesg, so I'm not sure this bug is even related. I leave it here for
people who have similar issues :)

Title:
  ExpressCard34 slot not hotplugable after boot

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have a 3,1 Macbook Pro. In 10.04, my ExpressCard34 slot was
  hotplugable after I added acpiphp to /etc/modules. On upgrade to
  12.04, the slot will only work if the device is plugged in at boot.

  Current behavior:

  Must plug in device at boottime, or the system will never recognize
  it.

  Expected behavior:

  Can plug in the device after boot and it is recognized.

  I should note, the attached documents were generated with apport-bug
  _after_ I rebooted with the device plugged in. If helpful, I can
  reboot again and attach additional files without the device plugged
  in.

  Thanks and I hope I'm reporting this against the right package.
