Hi all, (I am not sure if this is the right address for this bug, but dm_* is the first function listed in trace) this happened when I tried dd-ing LV, which resides on RAID10 sw storage, to network via netcat. The actual user-visible manifestation was segfault of dd that was used for reading. On first request the error reported was "unable to handle kernel NULL pointer dereference...", but on subsequent tries this changed to "general protection fault", see below. HW is a bit dated, but had no problems with it up to now, and SW raid is used here. Kernel was 4.2.4. Is this the right mlist for such bug?
Hi Yes the issue is known - but source is not fully known. I've opened public BZ: https://bugzilla.redhat.com/1279941 There is some potential fix - but unclear what it solves: http://git.kernel.org/linus/ad5f498f610 Regards Zdenek -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
