https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257082 --- Comment #19 from Hans Petter Selasky <hselasky@FreeBSD.org> --- Hi, I see in the log that the time between interrupts is unstable. The delta on MFINDEX should be close to 8*8 = 64 microframes.

Should output something like this: xhci0: <Intel Sunrise Point-LP USB 3.0 controller> mem 0xdf210000-0xdf21ffff irq 16 at device 20.0 on pci0 xhci0: 32 bytes context size, 64-bit DMA --HPS -- You are receiving this mail because: You are the assignee for the bug.
