Re: [microblaze-uclinux] 10 msec number of ticks bug..
John,
From the priliminary test i did today, the patch that you posted for
the "stability under heavy load" seems to be solving my problem. My
interrupts is about 300 per second (2uarts, timer, i2c and etherenet).
One of the way i could reproduce the problem earlier is to do
repeated tftp followd by netflash in a loop. The posted fix seems to
solve this problem. I am not getting any more crash. I need to run
this for few more days to check ntpd daemon hanging the system .
John, i also get the following error sometimes. I posted this in
uclinux-dev and did google-ing and i didn't get any convincing
answer/reasons for the occurance. Most of the message points as a
harmless problem although i am not sure on this. Do u have any idea on
this/usual suspects.

Can you please try the patch I posted a few minutes ago, and see if it makes any
improvement on your bug?
Thanks,
John
