  "message": "[rng] Check for several functioning RTC interrupts\n\nCommit 74222cd (\"[rng] Check for functioning RTC interrupt\") added a\ncheck that the RTC is capable of generating interrupts via the legacy\nPIC, since this mechanism appears to be broken in some Hyper-V virtual\nmachines.\n\nExperimentation shows that the RTC is sometimes capable of generating\na single interrupt, but will then generate no subsequent interrupts.\nThis currently causes rtc_entropy_check() to falsely detect that the\nentropy gathering mechanism is functional.\n\nFix by checking for several RTC interrupts before declaring that it is\na functional entropy source.\n\nReported-by: Andreas Hammarskjöld \u003cjunior@2PintSoftware.com\u003e\nSigned-off-by: Michael Brown \u003cmcb30@ipxe.org\u003e\n",
