A bunch of people whose machines appear to be spending 50% CPU time in softirq processing. Some find that `noapic' fixes it and some dont. Some are on x86_64, some are on x86. I suspect we have multiple bugs here. It's quite a mess. Could the reporters please, via a reply-to-all to this email: a) test 2.6.14. b) summarise the current status of your bug (what CPU type, what are the symptoms, any known workarounds, etc). c) Generate a kernel profile (see Documentation/basic_profiling.txt) Generally, let's get a bit of action happening here and see if we can get these relatively long-standing regressions fixed up, thanks. ^ permalink raw reply [flat|nested] 2+ messages in thread
