The old --check section looked for log strings that do not exist in the
xhcid codebase ("xhcid: using MSI/MSI-X interrupt delivery" etc.).
All six grep patterns were fictitious — the script was written ahead of
P0-A1 anticipating different logging.
Rewrite to match actual debug-level output from xhcid:
irq_reactor.rs:208 — "Running IRQ reactor with IRQ file and event queue"
(irq_file is Some — this is the main proof that interrupts fired)
irq_reactor.rs:125 — "Running IRQ reactor in polling mode."
(irq_file is None — must NOT appear in a passing run)
main.rs:88 — "Enabled MSI-X" (debug, MSI-X configured)
main.rs:95 — "Legacy IRQ <n>" (debug, INTx fallback)
main.rs:143 — "XHCI <pci_name>" (info, controller detected)
Also fails if both polling and IRQ-driven mode appear in the same boot.
