HP Pavilion 23 AIO - System repeatedly freezes during testing

[Jeff Lane ]

The system seems rather unstable. Several times during testing, it would just freeze. I thought, perhaps, this has to do with the Broadcom Wifi/BT combo as the freezes seemed to happen alot during testing involving either Bluetooth or Wireless, but it also froze up a few times outside of those times.

There is no indication in the logs that anything is amiss, the system simply locks up hard and has to be power-cycled to resume a working state.

@Acelan, Hi Acelan, could you please take a look at this bug ? thanks

Jeff Lane, could you please provide the full computer model as noted on the sticker (ex. HP Pavilion 23-b010 All-in-One Desktop PC)?

Hello Christopher,
No, this model name is all we have here.

Also, after the Wifi / BT module has been removed, this system seems working with 12.04.4
This probably the root cause of this issue, therefore I will mark this bug as Invalid.
For those who is affected, please feel free to open a new bug for it.
Thanks
