Hi all,
first of all...sorry for my english ;)
I had a strange problem at boot time. After a reboot it disappeared, but any
way I`m interested what happened, especially with this superblock
inconsistency...

Hi Mathias,
I don't know if this is your problem. But I have had the same DMA problem when
I overclocked a motherboard and the FSB was not divisible by 33( This was on a
Abit BP6 ). When it was not overclocked DMA worked great.

Hi all,
thanks for your mail. I also know that problem, but I didn`t overlock the
System. I think more and more that my problem hangs together with the
removeable-frame (it`s quite a cheap plastic one). Does anyone have any
experiences in this direction? What kind of removeable frame would be
bet
This a report about real production experiment using both Linux
software RAID and a Mylex hardware RAID controler (real production
tend to be even harder than tests, even on a lower load, since
more special situations append).

Anyone used the DC690 under Linux? Its a PCI card, 2 IDE busses,
no CDROM support, with 4 30pin SIMM slots. Supposedly does mirroring,
all of which is transparent to the OS. It doesn't require any DOS
drivers. Any pointers would be apprectiated.

I removed the Mylex controler, and since it's a production server,
I cannot do experiments on this one, so I cannot get any more informations

A new elevator was introduced into 2.2.16, that may be affecting
results. Try using elvtune from util
