Comment 54 for bug 1808418

I just installed a few kernels to see if I could narrow down the latest regression, and this is what I found:

- 5.7.0-050700 boots fine
- 5.7.5-050705 exhibits the problematic behaviour (does not boot)
- The latest kernel (5.13.7-051307) also does not boot

I doubt this is helpful, but these are the last log lines shown on 5.7.0 on a successful boot right before the GUI kicks in; I'm not sure if they're meaningful since they're just a few lines from the log as a whole:

[ 5.999124] ACPI: \_SB_.PCI0.LPCB.EC__.HKEY: BCTG evaluated but flagged as error
[ 5.999126] thinkpad_acpi: Error probing battery 2
[ 5.999135] battery: extension failed to load: ThinkPad Battery Extension
[ 8.097361] Bluetooth: hci0: command 0x1001 tx timeout

I guess at this point I need to do another bisect between 5.7.0 and 5.7.5. Here goes...
