Re: FYI: DMA/33 and kernels
I have managed to significantly reduce the error rate by turning OFF
everything in the bios settings that might improve the performacne of IDE.
This includes read-ahead, multi, IDE-PCI bursting, etc. Then I turned the
items back on in hdparms. Now down to a half-dozen errors per day with
2.0.35. I think some things were done after 2.0.32 to "improve"
performance of the IDE but I am going to have to diff the two drivers to
make sure. Something DEFINATELY changed between 2.0.32 and 2.0.33+. I
suspect that a delay between operations was shortened since most of my
errors appear to be that the drive is busy when a command to it is issued
meaning either that the ide driver does not wait long enough for a command
to complete or that it times out too quickly waiting for a command to
complete.
Might be time to do some hacking on ide.c
