vt6306 patch ready for 2.6.9-1.681_FC3 kernel (940 bytes, patch)

Description Alex Butcher 2004-11-18 10:16:41 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)
Gecko/20041111 Firefox/1.0

Description of problem:
Rev. 46 and below of the VIA 6306 Firewire/IEEE1394 controller
incorrectly reports its maximum packet size as 2, causing the kernel
to fall back to 512 as a default. It should use 2048 for best
performance. These controllers are very common and cheap enough to be
widely used.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Check kernel source
2. Observe missing VT6306 workaround
3. *sigh*

Actual Results:  After pulling myself together, I resigned myself to
having to rebuild the ohci1394 module locally.

Expected Results:  The ohci1394 module detected I had a flawed
controller, and worked around it.

Comment 2 Dave Jones 2005-07-15 19:21:38 UTC
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

Comment 4 Warren Togami 2005-07-25 03:08:39 UTC
Can you please talk to upstream about including this patch?  If a patch wasn't
included in upstream kernels from 2.6.9 through 2.6.12, maybe there is a good

Comment 5 Dave Jones 2005-10-03 00:00:41 UTC
This bug has been automatically closed as part of a mass update.
It had been in NEEDINFO state since July 2005.
If this bug still exists in current errata kernels, please reopen this bug.

There are a large number of inactive bugs in the database, and this is the only
way to purge them.

Thank you.
