After updating to todays tree, I have two machines
that stop booting after TSC init.
The last things printed are..
tsc: Refined TSC clocksource calibration: 2933.328 MHz
clocksource tsc: mask: 0xffffffffffffffff max_cycles: 0x2a483edfd02, max_idle_ns: 440795320705 ns
Switched to clocksource tsc
Then the cursor blinks, but booting doesn't continue.
I'll debug more in the morning..

False alarm. Or at least, not TSC related.
It's the same blk-mq bug that Guenter Roeck diagnosed a few hours ago.
