| |
This happened on Alpha (Miata, Digital Workstation 500au), with plain 2.6.15 when trying to run esd to talk to ALSA (snd-es18xx). In earlier versions this did not happen, however sound still did not work properly -- it was looping with no interrupts counted in /proc/interrupts for that device. Kernel was built with CONFIG_ALPHA_GENERIC, as opposed to CONFIG_ALPHA_MIATA because CONFIG_ALPHA_MIATA for some reason disabled serial interrupts.

(identical entries followed in the log).
This looks similar to what was reported for 2.6.15-rc1-mm2, except that this is 2.6.15. -- Alex Belits
