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. Please re-try.

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.
