Hi Jan, I bisected [1] to f1ed0450a5fac7067590317cbf027f566b6ccbca. Fortunately further investigation showed that it is not really related to removing APIC timer interrupt reinjection and the real problem is that we cannot assume that __apic_accept_irq() always injects interrupts like the patch does because the function skips interrupt injection if APIC is disabled. This misreporting screws RTC interrupt tracking, so further RTC interrupt are stopped to be injected. The simplest solution that I see is to revert most of the commit and only leave APIC timer interrupt reinjection. If you have more elegant solution let me know.
