6.8.0 Kernel warning
Hello all, There is something wrong in the was the 6.8.0 has been compiled. 6.7.5 has no such issues. Since this is a problem in the BTRFS module I believe this should be fixed asap in order to gice us the peace of mind that our data remains secure.

USB Modules)
I am running 6.3.5 on my ReadyNAS Ultra 2 Plus and all works fine. My Problem ist, i need to add the OneWire USB Modules to my system for a Home-Automation solution. This was my approach to get my target: I open ... http://kb.netgear.com/app/answers/detail/a_id/2649/~/gpl-open-source-code-for-programmers ... and found for "ReadyNAS OS 6(ReadyNAS 200)" the download link... http://www.downloads.netgear.com/files/GPL/ReadyNASOS_V6.3.5_WW_src.zip ... and unpack this zip in a /usr/src/ReadyNAS/ReadyNASOS directory. In this zip i found two posible directories (linux-3.12.43-52.6 and linux-3.12.43-52.6-alpine), which are seems to be the correct kernel source for ReadyNASOS 6.3.5 . I use linux-3.12.43-52.6 and so i do ... cd /usr/src/ReadyNAS/ReadyNASOS/linux-3.12.43-52.6 make distclean # seems to work fine make olddefconfig # seems also to work fine ... an now i try at first to compile the hole kernel without any modifications or additional modules with (to check, if .config is correct created) ... make This takes a longer time (>30 minutes) and multiple files can be correct compiled and linked but then i get the message ... .... CC drivers/pci/msi.o CC drivers/pci/htirq.o CC drivers/pci/ats.o drivers/pci/ats.c: In function 'pci_enable_ats': drivers/pci/ats.c:68:52: error: 'struct pci_dev' has no member named 'physfn' struct pci_dev *pdev = dev->is_physfn ? dev : dev->physfn; ^ drivers/pci/ats.c:70:19: error: 'struct pci_dev' has no member named 'sriov' mutex_lock(&pdev->sriov->lock); ^ drivers/pci/ats.c:78:21: error: 'struct pci_dev' has no member named 'sriov' mutex_unlock(&pdev->sriov->lock); ^ drivers/pci/ats.c: In function 'pci_disable_ats': drivers/pci/ats.c:117:52: error: 'struct pci_dev' has no member named 'physfn' struct pci_dev *pdev = dev->is_physfn ? dev : dev->physfn; ^ drivers/pci/ats.c:119:19: error: 'struct pci_dev' has no member named 'sriov' mutex_lock(&pdev->sriov->lock); ^ drivers/pci/ats.c:123:21: error: 'struct pci_dev' has no member named 'sriov' mutex_unlock(&pdev->sriov->lock); ^ make[2]: *** [drivers/pci/ats.o] Error 1 make[1]: *** [drivers/pci] Error 2 make: *** [drivers] Error 2 All Steps are done direct on my ReadyNAS (no crosscompile). I (think) i have all necessary build dependencies installed (build-essential, libncurses5-dev). My surmise is, the creation of .config is not correct. Where can i found/get the correct (and working) kernel .config for the 3.12.43 Kernel on ReadyNASOS 6.3.5 ??? BTW: Does anyone know, what are the difference between linux-3.12.43-52.6-alpine and linux-3.12.43-52.6 in the src zip-file and what is the purpose of the -alpine kernel?
