Is this a regression? If so, which versions were not affected?
How hard to reproduce? Wasn't it during resume from hibernation?
IRQ isuses may be a red herring, this code here is a busy wait under
spinlock. There are a few of those, they cause various problems.
if (xhci_handshake(&xhci->op_regs->status,
STS_RESTORE, 0, 100 * 1000)) {
xhci_warn(xhci, "WARN: xHC restore state timeout\n");
spin_unlock_irq(&xhci->lock);
return -ETIMEDOUT;
}
This thing timing out may be close to the root cause of everything.

Michal
