That will take a (longish) while to do. I've just managed to boot with PXE and 2.6.23.9 and I have come to the following: * softraid still works * sata_mv is a bit slower than the proprietary highpoint drivers (I get 300MB/s from my array rather than 400MB/s) * they array works * the content of the array seems to have shifted 'down' a bit, that's probably why it won't boot. it's a tad weird, but I can see the data just fine when I dump the content of the drives, but it seems to be in the wrong place. I'll recreate my volumes with sata_mv now, see if it will work like this. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
