tuo: transmit FIFO underflow: threshold raised to 256 bytes.
My OS is Compaq True64 system version 5.1.
Any suggestions.
Thanks in advance.

SolutionChange the parameter
% /sbin/sysconfig -q tu
tu:
StoreAndForward = 0
to 1 to enable store and forward mode without using DMA buffers. Of course, your packet latency will be greater, but it sounds like your system is crippled anyway (and you
probably wouldn't notice the increased latency).

Re: threshold raised to 256 bytes
I have the same problem but when I launch
/sbin/sysconfig -q tu
The system replies with: framework error: subsystem 'tu' not found.
I tried also tu1
Thanks.

Re: threshold raised to 256 bytes
you should have tu, if you have 5.1.
Can you post ifconfig -a?

# kdbx -k /vmunix /dev/mem
(kdbx) patch tu_sf_mode=1
this procedure must be repeated each time a new kernel will be created.

Re: threshold raised to 256 bytes
As I typed the command you showed me, the system replied with:
thread 0xfffffc007fe14a80 stopped at [thread_block:2376 ,0xfffffc00002c2490] Source not available
warning: Files compiled -g3: parameter values probably wrong
However I typed what you suggested and it replied with a "1".
I think I did it right and it seems to work now.
I'm sorry I can't give points.
Thanks.

Re: threshold raised to 256 bytes
Is your question answered? If so, would you be so kind to award some points for those, who gave you a hint?
greetings,
Michael
