One piece at last... I have tried - 2.6.11 - 2.6.11 + libata-dev1 + netdev1 + shrinkers-at-tail + 1Gb-lowmem Bot work fine and survived several gigas dumped both through smb and afp. Happy man ;). If there was something strange, it must be in -mm. rc5-mm1 did not work, but plain 2.6.11 works. I will try 2.6.11-mm1 on monday... Just a note. Net throughput seems a bit slower in the second case (measured with iftop). And it degrades over time. With a 8 Gb copy, it started at about 50Mb/s and dropped to 25 at the end. Not sure if the one to blame is linux or osx... Hardware (just for the record): 2 x PDC20319 (FastTrak S150 TX4) (rev 02) 6 x 250Gb Maxtor 7Y250M0 YAR5, 3 on each.
