I've read the "slab corruption of hpsb..." thread (John Mock, Oct 10 2003) and the Alastair Tse's bugreport in http://bugme.osdl.org/show_bug.cgi?id=1258, but not sure if related.
Running 2.6.0-test7, too. I have lost most of the directories from /home/me (ext3). When the loss happened, I was probably running at least two downloading programs, compiling and testing the camera driver. The problem seems to be related with the "slab error" messages, since the two only errors in my logs appear approx. at the same time the loss happened.
Both errors are right after the "pwc Closing video device" message (an USB related issue, as in John Mock's case?). May videodev's "has no release callback" message be related, too?
The partition is clean, according to fsck.
