Maybe somebody has experienced similar problems like this:
I am running linux (Debian Woody) on
MSI KT3 Ultra2-R (VIA KT333)
Onboard Promise PDC 20276 "FastTrak Lite"
2 IBM HDs 120GB on the PDC: raid0 as boot-HD using Promise raid (I also have to run Win98SE, so no OS-Software raid possible)
The Problem:
The original Debian kernel (2.4.18-BF) doesn't know the PDC but has ataraid compiled in. I can give it ide2, ide3 boorparameters, so it finds the disks and is able to boot from them. The performance is <2MB/s and high latency, though (no DMA for the disks and without the PDC-driver; hdparam can't set them to DMA either without the driver). So naturally I want to update the kernel.
I have been running 2.4.20 standard on an MSI KT266-R with the PDC20265 with a similar configuration for quite a while with pdc-ataraid and without problems.
If I compile the kernel for my new system though, I get kernel panics at boot as the kernel is unable to find my root-partition (on 72:06). Upon closer examination of the bootmessages there is absolutely no trace of the pdc-ataraid driver giving any sign of life, although it is statically compiled into the kernel:
... CONFIG_BLK_DEV_ATARAID=y CONFIG_BLK_DEV_ATARAID_PDC=y ...
I have tried:
1. Compile the kernel 2.4.20 with PDC driver (who doesn't know the 20276 natively) and pdc-ataraid
2. Compile the kernel 2.4.21-pre4 with the new PDC driver (who does know the 20276 natively) and pdc-ataraid
3. Compile the kernels without the PDC driver but pdc-ataraid (to try the same setup as with my 2.4.18-BF kernel)
The result is always the same - kernel panic, device 72:06 not found.
I get the kernel to recognize the disks (and the PDC for the kernels with the drivers) in all configurations, so that is not the problem.
I get no sign of the pdc-ataraid driver though. If I compile the HPT-ataraid in on top, I get a kernel message of it saying that no raid-array could be found (surprise...)
Who can help? Running native software raid is not an option due to the mentioned Win98SE on the same disks. Why isn't the pdc-ataraid driver giving any output? Other suggestions?
Thanks in advance!
