[SOLVED] System freezes after sleep since update

seth · 2024-12-28 19:40:09

lsmod | grep 7925
cat /proc/cmdline

There's no way the module gets loaded if it's actually in the module_blacklist

Nothing shows up for lsmod.

$ cat /proc/cmdline

I can turn on BT in my DE and it begins to function and am able to connect to it.

dmsg logs after enabling in DE:

[32061.141656] Bluetooth: hci0: HW/SW Version: 0x00000000, Build Time: 20241104133214

[32063.184452] Bluetooth: hci0: AOSP extensions version v1.00
[32063.184459] Bluetooth: hci0: AOSP quality report is supported

I also connected a BT controller to it.

I figured the DE BT gui would not see any BT devices or the device would not even function. Ah well-- I'll just make sure that BT is disabled in the DE.

mt7925e isn't used, but your bluetooth is

which was recently added to mt7925, https://www.spinics.net/lists/linux-blu … 15985.html
Try

module_blacklist=btusb

Does this disable all bluetooth devices that use this driver?

I'm thinking it does...

here is the device when plugged in via USB:

Yes - wasn't that the point?

I was trying to disable the mt7925e, only.

Are you actually sure you're using the mt7925e based one (assuming you've multiple and mt7925e is blocked)?
Do you still have freezes after suspending the system?

rfkill

rfkill

I've been only troubleshooting with one. After you suggested blacklisting btusb, I started using the USB dongle.

rfkill:

ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0     blocked unblocked

this is with mt7925e blacklisted.

When I plugin the usb BT dongle:

ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0     blocked unblocked
 1 bluetooth hci1   unblocked unblocked

interestingly enough, blueberry only functions on the hci0 device. So, if i

rfkill block 0

the BT gui disables and doesn't interact with the hci1 device.

Maybe I need a different bluetooth manager. My DE is cinammon.

With hci0 blocked (mt7925e) and hci1 unblocked, suspend works fine.

See whether https://www.projectgus.com/2014/09/blac … rom-linux/ rids you of the undesired device (w/o blacklisting btusb, but you'll probably still have to blacklist mt7925e)

Thanks for the link, seth. That is something to save for later.

I created a rules file with the following line:

# MT8725e should be disabled                            
# 09:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7925]
#       Subsystem: Foxconn International, Inc. Device [105b:e112]
#       Kernel modules: mt7925e
SUBSYSTEM=="usb", ATTRS{idVendor}=="0489", ATTRS{idProduct}=="e124", ATTR{authorized}="0"

I also removed the blacklist in the kernel command line.

The bt device no longer shows up when using rfkill, udevadm, or lsusb -tv.

Now, I need to figure out what happened to the wi-fi side of the MT7925 device. It used to work in previous kernel versions (6.12.1) and now it is considered to be unclaimed. It used to be functional when I installed this motherboard as I needed to downloard the rt8125 drivers for the ethernet chipset (November 2024).

So, something screwing going on, now that the driver is missing. Maybe this'll get resolved in 6.13?

lspci -k
lsmod | grep mt7925e
mpdprobe -v mt7925e
mpdprobe -c | grep -v alias | grep mt7925e

I got it working. Thanks. I forgot I had a blacklist file in modprobe.d. The last command reminded me that I did that.

Kernel 6.12.8 seems to have resolved the BT issue.

Can confirm. With 6.12.8, wake from Sleep working again with BT enabled.
