touchbar and wifi broken for 2023.12.24-t2
schnell18 opened this issue · 1 comments
I followed the t2 offical installation guide for ArchLinux to install the
2023.12.24-t2 on my 2019 macbookpro with Intel i9-9880H, 32G memory, 1T NVME
drive and touch bar. When it was booted on the USB drive, the touchbar and wifi
worked as expected. They no longer work when the macbook is booted on the hard
drive. The touchbar is compleltely dark and doesn't respond to any touch. Error
messages from dmesg and journalctl indicate the tiny-dfr keeps crashing due
to segfault.
The dmesg log snippet:
[Sat Jan 27 08:21:13 2024] tiny-dfr[513]: segfault at 0 ip 00007bf945c78edd sp 00007fff93f50eb8 error 4 in libc.so.6[7bf945b44000+15a000] likely on CPU 5 (core 5, socket 0)

The journalctl log snippet:

The second issue is the wifi doesn't work either. Typing iwctl station wlan0 connect <ssid> returns immediately
rather than displaying prompt to enter password as when booted on USB drive.
Attached are the journalctl and dmesg logs.
reboot to macOS and try booting into Linux again.
