Re: help with a build-user and build-user-plugin failure

[Claudio Fontana <cfontana@suse.de>]

Hi all,

and thanks for the help, after a lot of fiddling and applying your suggestions (and a reboot !?)
now things work.

The only thing I am left seeing (also on master) is with check-tcg:


Remote 'g' packet reply is too long (expected 312 bytes, got 560 bytes): 0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000040008004310000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000010063000000000001006340000000082009207000000000000000000000000000000000000000000000000
Traceback (most recent call last):

a number of times during the test.

Seems not to break anything, but I wonder if it is expected or it would need suppressing?

Thanks again,

Claudio
