Hello, listers! I hope those of you who are experts in kernel bugs or interaction of kernel with the hardware can help me with this. Since I installed Redhat 7.1 I started to get the messages that RedHat cannot communicate through DMA with my hard drives. I know for sure that my hard drives can communicate through DMA, plus I was never getting similar messages before. Shon suggested for me to check whether UltraDMA support was compiled into my kernel, but I, firstly, do not understand why it should be included into kernel, and secondly, why would Redhat ignore including UltraDMA support in the first place. Iam therefore attaching the complete log from the messages buffer ring produced by the `dmesg' command. Please let me know if you have any idea and where should I look for possible solutions. WIndows 2000 is very happy about my drives, whereas Linux complains about them. However, after kernel disables DMA transfer mode, it goes pretty fine. Please ignore any messages about SWAP... Best and thanks in advance, Vic -------------- next part -------------- A non-text attachment was scrubbed...
