Description of problem: IO programs fail with Fujitsu U320 SCSI disk MAP-Series, when Fujitsu U320 SCSI Disks have too low firmware level, Adaptec controller AIC7902 is used Adaptec driver has a version < 1.3.8 As long as we had system which complies to above requirements, we did not have any problems. Now one of our customers was using a kernel from RHEL 3.0 beta 1 for i386, and we got in some cases incorrect write operations - meaning that the return-code from write was not equal to the length of the written record. For the moment it would be enough if you could compare the source of your aic79xx 1.3.10 with the actual source from Mr. Gibbs, which is available on people.freebsd.org/~gibbs/linux, to check if you missed changes done be Adaptec to fix the problem AIC79xx with Fujitsu SCSI disks Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: please check also bug 102194
------- Additional Comments From Winfrid.Tschiedel.com 2003-10-01 02:38 ------- Hello Tom, Many thanks, the problem did not occur with newer kernels, so you can close this bug. Winfrid PS.: You should keep also an eye on bug 102194, we are have still a bad READ performance with the Enterprise Kernel ( 2.4.21-3EL ) compared to e.g. 2.4.20-19.9.smp
