AW: [PATCH]: [MPC5200] Add ATA DMA support
Tim, Grant, just an info. Very often the Bestcomm-FEC crashed without any error logs if I initiate a transaction over FEC and save the file to disk (I rememeber I have read something like that). A restart of FEC don't work. But no I figured out, if I connect to the other ethernet port of our board (natsemi) the FEC will awake to life again, if I initiate a new transaction over natsemi. This seems a little oddly to me.

Tim, Grant here are some more information. I think there is a also a problem with memory after FEC crasched.

Hi guys, We tried to get the SUSE guys to push the patch into openSUSE 11.1 release and the tests came back negative here too with regards to FEC support; for some odd reason, it does this; https://bugzilla.novell.com/show_bug.cgi?id=445856#c10 There is some weird interaction here, but I can't imagine what it might be. Tim, did you ever see any ethernet problems like this? -- Matt Sealey [EMAIL PROTECTED] Genesi, Manager, Developer Relations ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

Re: AW: [PATCH]: [MPC5200] Add ATA DMA support
Hmm even with DMA built in my disk (Seagate 5400.8) still configured for PIO4. This is probably my fault. Tim, could you respin the patch anyway since it doesn't apply cleanly to the 2.6.27 kernel? :) This did work for me once but we were still using a SUSE kernel (from 11.0) to patch it onto and another interrupt controller patch crippled performance so it wasn't a really good test.. -- Matt Sealey [EMAIL PROTECTED] Genesi, Manager, Developer Relations Lehmann, Hans (Ritter Elektronik) wrote: We take a vanilla kernel with rt11 patches from Ingo Mollnar.
