Firstly enable lvm debugging. lvm.conf: log { file="/tmp/lvm2.log" level=7 } Compare the lvm log files for the kernels to see where it's going wrong. Then take complete straces (incl. read/write data) of the lvm process with each kernel and again compare them. [Or put files on web and send URLs.] [To check for repeat of old problems with related symptoms:] Were both kernels compiled with the same compiler version? Which version? Does it make any difference if you rebuild lvm with --disable-o_direct?
