Hi Sebastian, I rolled back my changes and removed IRQF_ONESHOT as you said and it is indeed working, no more hanging out at boot. drivers/i2c/busses/i2c-exynos5.c 760 ret = devm_request_irq(&pdev->dev, i2c->irq, exynos5_i2c_irq, 761 IRQF_NO_SUSPEND, 762 dev_name(&pdev->dev), i2c); Should we keep that fix?
