hi all,
I just subscribed to the list, and am looking for some suggestions.
I have a device driver for a RS485 card that does microlan
communications between several devices. The driver was written a couple
of years ago using the 2.2 kernel in RH 6.1. It's was updated for 2.4
kernel when RH7.3 was released and has been working fine. RH8.0 is
apparently a different story, as there appears to be problems with
scheduled timeouts (polling intervals) and maybe some interrupt issues.
My question is are there any known problems ( RH kernel 2.4.18-3)? I
know I'm dealing the revamps in the scheduler and timer areas and then
there's the shift from gcc 2.96 to 3.2.
Thanks for any suggestions,
Harlan
HZ value for i686 has been modified from 100 to 512 in RH 8.0.
If you use this HZ value directly in your driver and , it could be a problem.
