Hello, gurus.
Recently I encountered the kernel "page allocation" error in the TIPC code.
I attached the backtrace printout.
I use 2.6.37 Linux version, which seems to use TIPC 2.0 (although I am not
sure, but the code is prom the Arago distribution).
All this runs in the embedded ARM system.
Although it seems to me irrelevant, but anyway - the largest packet
transferred by me is 15KiB.
I will be very thankful for any comment about the issue.
