I'm still running an -rc5 kernel with ADMA switched off entirely and I can't reproduce the problem. How is everybody else reproducing this? I've been successful installing bonnie++, then going to a large XFS partition and running "bonnie++ -u 1000:1000" and letting it run through, all defaults. It doesn't cause the problem I was seeing in -rc5 with ADMA on, when I switch ADMA off, so I think this is sufficient to fix it. Others have reported differently. Did you guys do: [EMAIL PROTECTED]:~$ cat /proc/cmdline root=/dev/sda1 ro sata_nv.adma=0 Or something similar? This is how Jeff suggested disabling ADMA and indeed the messages about its use disappear from dmesg. -- Cheers, Alistair.
