Ah hah. You appear to be missing CONFIG_RTC_DRV_ALPHA in the new kernel, so you have no support for the RTC at all.

Grr. Naturally, the old kernel obfuscates which timers are being delivered where. So a direct comparison doesn't appear possible. But those separated numbers seem uncomfortably low. I've just pushed a new branch to git://github.com/rth7680/linux.git axp-qemu-7 Please try that with CONFIG_ALPHA_WTINT disabled. I'd like to eliminate that as a source of uncertainty for your system. r~ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
