I just set up some new systems, and loaded both the "sd" and "sg" drivers, so I can access their SCSI disks and the SCSI backplane (with monitoring software).

However, I find that if the sg driver is loaded, the LVM2 tools (LVM2.2.00.22) get stuck in an infinite loop scanning the /sys hierarchy (witnessed using strace):

/sys/block/sda/device/generic/device/generic/device...

Removing the sg driver from the kernel is a workaround, but I'd like to be able to add it back at some point.
