Re: [microblaze-uclinux] Heavy packet load and SIGALARM

[Prasad <ndprasad@xxxxxxxxx>]

I guess the first problem never got solved in the microblaze 2.4.xx .
Never tried out 2.6 kernel yet to check the same problem. i changed my
design to not use the signal handler in the module that receives so
much of the packet.
