My Aeon Labs ZWave USB stick doesn't work anymore since 5.11.12-arch1-1:
[ 193.677337] usb 2-2: new full-speed USB device number 5 using xhci_hcd
[ 193.818112] usb 2-2: New USB device found, idVendor=0658, 
idProduct=0200, bcdDevice= 0.00
[ 193.818117] usb 2-2: New USB device strings: Mfr=0, Product=0, 
SerialNumber=0
[ 194.372999] cdc_acm 2-2:1.0: ttyACM0: USB ACM device
[ 194.373197] usbcore: registered new interface driver cdc_acm
[ 194.373199] cdc_acm: USB Abstract Control Model driver for USB modems 
and ISDN adapters
[ 200.173616] cdc_acm 2-2:1.0: acm_port_activate - usb_submit_urb(ctrl 
irq) failed

It works fine on 5.11.11-arch1-1 and on a Fedora 34 Live USB with kernel 
5.11.16.
Arch's 5.11.16 doesn't work and latest Arch's linux-lts doesn't work 
either.
This led me to believe that this could be due to an Arch configuration 
change happened between 5.11.11 and 5.11.12 (AFAIK they don't carry any 
additional patch).
This is the only one I've found: 
https://github.com/archlinux/svntogit-packages/commit/0b94106e755810659ccd9accfa4821bc3b429d34#diff-3e341d2d9c67be01819b25b25d5e53ea3cdf3a38d28846cda85a195eb9b7203a

Basically they added CONFIG_IDLE_PAGE_TRACKING=y. They backported the 
same configuration change to linux-lts. I don't know if this makes any 
sense, I'm running out of ideas.
