Ok..sorry for html mails.. I recompiled kernel from vanilla adding PIO mode forcing and nothing changes because I still have to use b43.conf with qos=0 option. If I don't bcm4312 doesn't connect. I attached new dmesg with or without b43.conf file.
The problem is not related to dma, I think, because even with pio forcing the connection (specially when is under pressure, when download traffic is high) at a time falls down and I have to reload b43. --- Ven 18/6/10, Gábor Stefanik <[email protected]> ha scritto: Da: Gábor Stefanik <[email protected]> Oggetto: Re: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01) A: "neubauten84" <[email protected]> Cc: [email protected] Data: Venerdì 18 giugno 2010, 17:41 2010/6/18 neubauten84 <[email protected]> > > Linux neubauten84-laptop 2.6.35-4-generic #5-Ubuntu SMP Wed Jun 16 18:53:19 > UTC 2010 i686 GNU/Linux > Is there a newer ubuntu kernel? > No. However. for debugging kernel issues, it is not a good idea to run distro kernels - try an official kernel.org release.
