I'm running 6.0-release p4, and this wasn't a problem in 5.4-release. I'm curious if this has been fixed in 6.1 or current or if I should file a problem report. I have a USB SD card reader. When I plug it in (with SD card inserted) FreeBSD detects it fine. Sometimes, however, it thinks the device is write protected and after displaying a couple of errors the kernel panics with a page fault. Keep in mind I have NOT tried to mount the device yet, I just plugged it in. The device worked flawlessly on 5.4 and has worked a couple of times on 6.0 release before. It also works fine on my XP laptop.
