If so, maybe a hint in there. WRT performance, this raises it from 2MB/s to 30MB/s for one user: https://listman.redhat.com/pipermail/ataraid-list/2002-December/001397.html my chip is pdc20271 hdparm -c 3 -d 1 -m 16 - X 69 /dev/hde hdparm -c 3 -d 1 -m 16 - X 69 /dev/hdg give me good results Also, this mention: https://listman.redhat.com/pipermail/ataraid-list/2002-December/001396.html When I set "CONFIG_PDC202XX_FORCE=y" to: "# CONFIG_PDC202XX_FORCE is not set" in the config file and then recompiled the 2.4.19 kernel, it solved my problems. Obviously there is something wrong with this code. Cheers; Leon
