** Description changed: Since the kernel upgrade to 5.6.0-1048-oem my Dell XPS 13 9380 starts to hang and finally freezes when I want to connect to my AV-receiver over bluetooth. All consecutive versions > 5.6.0-1048-oem show the same behaviour, hence I'm still booting 5.6.0-1047-oem currently. The only HW change I did to my Dell XPS 13 9380 was changing my SSD to a bigger Samsung SSD 970 EVO Plus 1TB, everything is as I ordered it. + I read about bluetooth vulnerability fixes in exactly the version where the problem started here: https://ubuntu.com/security/notices/USN-4752-1 + Maybe that has something to do with the issue? + Can somebody reproduce this issue? + lsb_release -rd ``` Description: Ubuntu 20.04.2 LTS Release: 20.04 ``` - - lspci - ``` - 00:00.0 Host bridge: Intel Corporation Coffee Lake HOST and DRAM Controller (rev 0b) - 00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (Whiskey Lake) - 00:04.0 Signal processing controller: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Thermal Subsystem (rev 0b) - 00:08.0 System peripheral: Intel Corporation Xeon E3-1200 v5/v6 / E3-1500 v5 / 6th/7th/8th Gen Core Processor Gaussian Mixture Model - 00:12.0 Signal processing controller: Intel Corporation Cannon Point-LP Thermal Controller (rev 30) - 00:14.0 USB controller: Intel Corporation Cannon Point-LP USB 3.1 xHCI Controller (rev 30) - 00:14.2 RAM memory: Intel Corporation Cannon Point-LP Shared SRAM (rev 30) - 00:15.0 Serial bus controller [0c80]: Intel Corporation Cannon Point-LP Serial IO I2C Controller #0 (rev 30) - 00:15.1 Serial bus controller [0c80]: Intel Corporation Cannon Point-LP Serial IO I2C Controller #1 (rev 30) - 00:16.0 Communication controller: Intel Corporation Cannon Point-LP MEI Controller #1 (rev 30) - 00:1c.0 PCI bridge: Intel Corporation Cannon Point-LP PCI Express Root Port #5 (rev f0) - 00:1c.6 PCI bridge: Intel Corporation Cannon Point-LP PCI Express Root Port #7 (rev f0) - 00:1d.0 PCI bridge: Intel Corporation Cannon Point-LP PCI Express Root Port #9 (rev f0) - 00:1d.4 PCI bridge: Intel Corporation Cannon Point-LP PCI Express Root Port #13 (rev f0) - 00:1f.0 ISA bridge: Intel Corporation Cannon Point-LP LPC Controller (rev 30) - 00:1f.3 Audio device: Intel Corporation Cannon Point-LP High Definition Audio Controller (rev 30) - 00:1f.4 SMBus: Intel Corporation Cannon Point-LP SMBus Controller (rev 30) - 00:1f.5 Serial bus controller [0c80]: Intel Corporation Cannon Point-LP SPI Controller (rev 30) - 01:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.
