Ok, I have not read the kernel sources etc, but why not use the swflush
(wich seems to be the problem, since ipx, elc and newer have hwflush and
are working stable) functions from 1.5 ? It had no problems (I am new to
sparc's, own a IPC and as far as I tried 1.5.3, it was stable, with 1.6
I get error 11 sometimes when using gcc, and yes, that tagged queuing
bug too). Or is the 1.6 kernel so different from 1.5.3 ? Sorry, I am no
kernel programmer, but just a thought, question.
