ZFS performance drops suddenly
Status in zfs-linux package in Ubuntu:

Bug description:
Run Phoronix Flexible IO / Random write benchmark.
After running the benchmark repeatedly multiple times (occasionally it can be
30 minutes or 8 hours), the performance drops suddenly. The only way (I know
of) to get back to high performance is reboot.

[Kernel-packages] [Bug 1883028] Re: Bluetooth devices don't reconnect after sleep.
My problem is even bigger. My bluetooth device does not work - BT Mouse and BT Headphone. I have tried to pair them, but the OS does not even find any device. I have Focal Fossa installed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1883028 Title: Bluetooth devices don't reconnect after sleep. Status in bluez package in Ubuntu: Confirmed Bug description: Bluetooth devices don't reconnect after sleep, or something along those lines. I have experienced this with a BT audio receiver and BT Keyboard. One way to repro is to switch BT pairing on multi-pairing keyboard, then switch back to Ubuntu. The BT connection state will be very confused, keyboard will not work. Another way to repro is to get a bluetooth audio receiver, pair it. Let the BT device (or PC?) sleep... now wake up the system. The audio will not play. BT UI slider says disconnected. If you click the slider it will go back to off. If you click it quickly >25 times, no joke, it will reconnect and work.

Title:
[linux-azure] Two Fixes For kdump Over Network
Status in linux-azure package in Ubuntu:
Confirmed
Bug description:
Microsoft would like to request two kdump related fixes in all
releases supported on Azure. The two commits are:
c81992e7f4aa1 ("PCI: hv: Retry PCI bus D0 entry on invalid device state")
83cc3508ffaa6 ("PCI: hv: Fix the PCI HyperV probe failure path to release
resource properly")
These are in the virtual PCI driver for Hyper-V. The customer visible
symptom is that the network is not functional in the kdump kernel, so
the dump file must be stored on the local disk and cannot be written
over the network.
The problem only occurs when Accelerated Networking is enabled. It’s
a relatively obscure scenario, which is why the problem has not
surfaced before now. But we have an important customer who wants the
“dump-file-over-the-network” functionality to work.
