Hey all, I just put the latest buildroot from svn on my gumstix. After doing so, mwlan0 doesn't come up as a device. I see the following errors during boot: cfio: module license 'unspecified' taints kernel. cfio: Unknown symbol kmalloc modprobe: FATAL: Error inserting cfio (/lib/modules/2.6.18gum/kernel/drivers/pcmcia/cfio.ko): Unknown symbol in module, or unknown parameter (see dmesg) dmesg just says "cfio: module license 'unspecified' taints kernel." Any idea what's going on here? I've tried playing with packages in menuconfig, but to no avail. |

Have you mixed older kernel versions with the new buildroot? Did you overwrite the old gumstix_buildroot directory with the old one? It sounds like you compiled a kernel module against a newer/older version of the kernel, or you tried to insert an old version of a module to a newer kernel. polychronis Chris Evans wrote: > Hey all, > > I just put the latest buildroot from svn on my gumstix.

This means that when Craig changed from SLOB to SLAB, all modules which use kmalloc need to be rebuilt. ACTION FOR CRAIG: Rebuild cfio binary. I'll need to check my i2c & robostix modules as well. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

I *have* to get these people to figure out their shit about letting us release this source code; it's starting to get a little silly...
