In kernel 2.2.16-17, the SG driver has introduced a bug, which is easily removed. The bug concerns the communication with the sym53c416 isa scsi card. It can be remedied by applying the 2.1.39 patch found here: http://www.torque.net/sg/ Kernel 2.2.16-17 is using the 2.1.38 SG driver, however patching to 2.1.39 would not be a risk (according to the documentation given at that link). regards, Bernhard Ege
