Hi,
I have tested 4.77 4.80 and git. All appear to have the same issue.

Hi,
I am using bluez-4.77 on a Gumstix Verdex kernel 2.4.32 patch 21
When I run:
sdptool records 00:80:37:2F:06:08"
from the Workstation Ubuntu 10.04 Bluez-4.6? to the Gumstix the Gumstix
hangs.
It does not hang completely but is very busy. It hangs for about 20
seconds and then releases for about 1 second
before it locks up again.
I couldn't find anything that could solve this kind of problem in the logs
between 4.6 and the git head. But anyway, could you give a try to 4.80, or
better yet, the git head[1]? and see if the problem still happens?
I have tried this on several different Gumstix with the same issue.
Changing workstations from Ubuntu 10.04 to Ubuntu 8.04 does make a
difference.
From Ubuntu 8.04 there seems to be no problem. blue-utils 3.26?
A really helpful piece of information that you could provide is the hcidump[2]
logs of both cases, just be sure to give hcidump the options "-V" (verbose
output) and "-t" (timestamps, to see where the hang happens).
Appreciate help
Thanks
