SD Card mounts first time but will not remount

I have this problem with an HP G62 Notebook PC, I was testing Natty Beta 1.

Also affects Natty Beta 2 iso.

Found out that if you suspend the laptop, when returning from suspension the micro SD, that has been left in the card reader, mounts again.

I can confirm this. If you unmount the card by just clicking "unmount" it can be remounted by just inserting it. If you click on "safely extract drive" it can't be remounted until next reboot.

Status changed to 'Confirmed' because the bug affects multiple users.

You are unmounting the card reader when you only need to eject the card from the reader which leaves the card reader mounted and able to read the next card inserted into it. There should be a second option, and in Linux Mint 12 it is 'eject' which is the correct option to enable the card to be safely removed.
A USB memory stick is unmounted before removal, but SDxx memory cards are ejected, leaving the card reader mounted and ready to read the next card inserted.

This bug has been reported on the Ubuntu laptop testing tracker.

Same problem with Ubuntu 11.10 e Ubuntu 12.04 beta2.
Packard Bell Easynote TJ65.

It doesn't work both with "Eject" and "Safely remove drive".

After 5 attempts (insert-eject) it works!

Precise 12.04 same issue.

Following the first 'Safely Remove':
$ dmesg | tail

It appears that the card reader port is powered off. Pulling the SD card and inserting into another system works - card opens right up.

I may be wrong but I believe "safely remove drive" will always unmount the internal card reader, and should only be used if you are using an external USB card reader and wish to remove it AND the card. I always use "eject" to remove an SD card from the internal card reader and can plug another card in and recognize the media without having to reboot.

You are correct in that 'eject' works. The issue is with 'Safely Remove". .

However the help files are ambiguous regarding this:

Safely remove an external drive
When you use external storage devices like USB flash drives, you should safely remove them before unplugging them. If you just unplug a device, you run the risk of unplugging while an application is still using it. This could result in some of your files being lost or damaged. When you use an optical disc like a CD or DVD, you can use the same steps to eject the disc from your computer.
To eject a removable device:
From the Activities overview, open Files.
Locate the device in the sidebar. It should have a small eject icon next to the name. Click the eject icon to safely remove or eject the device.
Alternately, you can right-click the name of the device in the sidebar and select Eject.
Safely remove a device that is in use
If any of the files on the device are open and in use by an application, you will not be able to safely remove the device. You will be prompted with a window telling you that "the volume is busy," and listing all the open files on the device. Once you close all the files on the device, the device will automatically be safe to remove. At that time you can unplug or eject it.
If you can't close one of the files, for example if the application using the file is locked up, you can right-click the file in the Volume is busy window and select End Process. This will force the entire locked up application to close, which could close other files you have open with that application.
You can also choose Unmount Anyway to remove the device without closing the files. This may cause errors in applications that have those files open.

I just found this bug today and I had the same issue here in ubuntu 12.04 with HP Pavilion dv6
