Ah, so this bug isn't actually caused by a patch but rather by a different config option. I think we can't do much about it, currently. The device has strange memory requirements and changing the split does actually break it. This cannot be fixed until andi kleen's mask-allocator is merged. This "bug" has always been there. > Working config file (on 2.6.25) is attached. > Diff to the non-working is below: > > --- working_config 2008-04-21 23:42:40.000000000 -0300 > +++ not_working_config 2008-04-21 23:55:28.000000000 -0300 > @@ -1,7 +1,7 @@ > # > # Automatically generated make config: don't edit > # Linux kernel version: 2.6.25 > -# Mon Apr 21 23:28:49 2008 > +# Mon Apr 21 23:43:04 2008 > # > # CONFIG_64BIT is not set > CONFIG_X86_32=y > @@ -228,12 +228,12 @@ > # CONFIG_NOHIGHMEM is not set > CONFIG_HIGHMEM4G=y > # CONFIG_HIGHMEM64G is not set > -CONFIG_VMSPLIT_3G=y > -# CONFIG_VMSPLIT_3G_OPT is not set > +# CONFIG_VMSPLIT_3G is not set > +CONFIG_VMSPLIT_3G_OPT=y > # CONFIG_VMSPLIT_2G is not set > # CONFIG_VMSPLIT_2G_OPT is not set > # CONFIG_VMSPLIT_1G is not set > -CONFIG_PAGE_OFFSET=0xC0000000 > +CONFIG_PAGE_OFFSET=0xB0000000 > CONFIG_HIGHMEM=y > CONFIG_ARCH_FLATMEM_ENABLE=y > CONFIG_ARCH_SPARSEMEM_ENABLE=y > > Can this be the cause? > > Thank you! > > Best regards, > Nelson > -- Greetings Michael. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
