Thanks. If the bug is in Linus's tree the fix must target 'sparc' not 'sparc-next'. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Thanks. > > If the bug is in Linus's tree the fix must target 'sparc' not > 'sparc-next'. Dave, Yes, indeed the bug is in Linus's tree. However, 'sparc' tree doesn't have DMA API change (e.g. commit b02c2b0bfd7ae) yet that introduced the panic. Looks like the DMA API changes have not merged into 'sparc' tree yet. In other words, 'sparc' tree doesn't have mentioned panic issue, nothing to fix there! However, 'sparc-next' is up to date (or more close to) linus tree and has DMA API change that cause mentioned panic issue. So I have send patch targeted for sparc-next. Let me know what should be the best tree to get this fix in and I will send v2.
