Ubuntu
linux-firmware package

Downgrading from most recent version fixes issue that upgrade caused, What do I do about that?

Asked by Jason Mitchell

I started getting a lot of wifi disconnects and whole system stuttering, I looked at recent upgrades and saw that linux firmware was recently upgrade.

I downgraded it with "apt-get install linux-firmware=1.201"

to replace the 1.201.5 and it stopped having issues, other then pinning the package so *I* don't have that issue, what should I do?

In dmesg, every time it happened there was a line that said

rtw_8822ce 0000:03:00.0: failed to do dpk calibration

after downgrading, that doesn't happen anymore, and the connection is rock solid, and that line isn't showing up in dmesg

in lspci the device shows up as "Hewlett-Packard Company RTL8822CE 802.11ac PCIe Wireless Network Adapter"

From the change log:

linux-firmware (1.201.5) impish; urgency=medium

  * rtw89_pci constantly drops connection with old firmware (LP: #1960933)
    - rtw89: 8852a: update fw to v0.13.30.0
    - rtw89: 8852a: update fw to v0.13.33.0

According to Bug #1960933 the change should affect RTL8852A devices only.

Do the system messages show anything about firmware loading for the wifi device, e.g. with a command like
dmesg | grep -i -e rtw -e fw -e firmware

If you manually download and install version 1.201.4 from https://launchpad.net/ubuntu/+source/linux-firmware/1.201.4/+build/23103354 does this also show the disconnects and the error messages?

You should consider creating a bug report.

Is the output from the dmesg/grep

I'll try installing that this evening thank you.

I've never made a successful bug report anywhere, so I generally go on the assumption it's me not the computer that's messing up, this one was just weird so I thought I'd try here.

Remarks:

Is "rtw_8822ce 0000:03:00.0: failed to do dpk calibration" the only message that appears with the disconnect, or are there also other messages?

The file that was changed between 1.201.4 and 1.201.5 is rtw89/rtw8852a_fw.bin, but your log does not show that it is used on your system.

Can you help with this problem?
