Maybe you could try > http://www.zip.com.au/~akpm/linux/patches/stuff/2.6.12-rc2-mm1.5.gz I'm not so sure, last week I had similar results with an external IEEE 1394 disk drive. On the first attempt it wasn't detected, in the 2nd and 3rd attempt detecting worked ok. After copying a data for like 2min the system paniced with no useful data in the log. Further attempts resulted in more hangs and panics. The kernel was the latest and greatest FC3 kernel, kernel-2.6.10-1.770_FC3. (I'm a 1h flight away from the system so can't do any more testing on that system) Ralf
