Here it goes. Did your tests which doesn't change anything. But I couldn't find the cpu= parameter in kernel-parameters.txt so I tried something else too: both kernels (with/out acpi): Parameter NO EHCI USED EHCI irqpoll 52MB/s 30MB/s idle=poll 58MB/s 58MB/s However idle=poll is not very power-saving (cpu fans at top-speed) I also tried other combinations so it were about 30 or so restarts. (BTW: Is it normal that you see Inode-cache hash table entries: 32768 (order: 5, 131072 bytes) Memory: 256468k/262080k available (1583k kernel code, 5060k reserved, 667k data, 136k init, 0k highmem) when you close your eyes?) IRQ thing? Hmm.. Looked at the Page of MSI for a new BIOS. It's an old board so I didn't expected a new one. Was wrong. So I did an update. (Someone shouts "Don't do it" in the background) Ok. Now with irqpoll I get 53/34 MB/s. Ideas? (I'm going to test all other problems I had with the prior BIOS). Bye.
