Yesterday I ran fsck on all disks and it took more than three times as much to complete under 2.5.2-pre9 than usual. I am running SuSE 6.3, MB is Asus A7v, controller ATA 33 + Promise PDC 20265. These are the results for a disk, (ATA 100 IBM 307030),for the other disks they are pretty the same. Resuslts for "hdpam -t /dev/hdg" Kernel 2.5.2-pre1 - 35 MB/sec Kernel 2.5.2-pre4 - 15 MB/sec Kernel 2.5.2-pre9 - 10 MB/sec For the rest, it seems pretty stable, but I still get kernel panic on cold boots from the AHA 2904 (AIC7850).
