Hi, while tracking down some timer related ugliness I stumbled over the timer driven function rt_secret_rebuild(), which does a loop over rt_has_mask (1024 in my case) entries and possibly some subsequent variable sized loops inside each step.
On a 300MHZ PPC system this accumulated to a worst case total of >5ms. I could not reproduce it with this magnitude, but applying heavy networking load is definitely triggering this behaviour. Shouldn't this be converted to a workqueue, which gets triggered by a timer instead of blocking the timer softirq and therefor the delivery of other timer functions that long ? tglx - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
