Hello everyone, I am not sure whether I am right in this mailing list or not, but I hope so... I am relative new to kernel development and especially to the device mapper. Currently I am developing a driver using the device mapper API. It works perfectly with one exception. After some time of heavy load every process that tries to access the mapped block device gets stuck in the uninterruptable state. I already checked every entry and callback routine in my driver, but it gets not stuck there. I also checked every lock I am using in my driver and every one of them gets released properly. I am pretty stuck at the moment, because I don't know where to look else for the problem and was hoping that some one of you might have experienced similar problems or an idea where to look for it. I don't know if it is important but I've noticed (using the kernel debug option for detecting hung tasks) that every process seems to hang in a write call and I've tried kernel versions 2.6.31 and 2.6.33. I would appreciate every bit of help because I am completely out of ideas! Regards, Anselm -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
