Description Greg Guldenschuh 2007-01-06 07:03:18 UTC

Description of problem:  This problem is in both FC5 and FC6 x86_64 NON ZEN
VERSION.  Running Hylafax on ttyS0, as soon as Hylafax answers the phone and
data transfer begins from the remote fax, the port appears to hang and nothing
will free it up.


Version-Release number of selected component (if applicable): FC5 and FC6 x86_64
NON Zen


How reproducible: Happens every time


Steps to Reproduce:
1.install either FC5 or FC6 x86_64 non Zen
2.install Hylafax and fax modem on ttyS0
3.send fax to Hylafax
  
Actual results: port appears to hang and remote fax gets line error.  


Expected results:


Additional info:  Dropping back to FC5 i386 completely eliminates the problem. 
Due to time constraints, I did not try FC6 i386.  The Zen version on FC6 x86_64
would not even recognize the serial port, but I believe that issue is addressed
in another report.  I would recommend checking FC6 x86_64 Zen to insure the
problem is not there once we get past the Zen taking over ttyS0 issue.

(This is a mass-update to all current FC6 kernel bugs in NEW state)

Hello,

I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.

http://fedoraproject.org/wiki/KernelBugTriage

I am CC'ing myself to this bug, however this version of Fedora is no longer
maintained.

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!

Comment 2 Jon Stanley 2008-02-08 04:25:53 UTC

Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA,
since no information has been lodged for over 30 days.

Please re-open this bug or file a new one if you can provide the requested data,
and thanks for filing the original report!
