darn....

I also tried with libata driver on the 2.6.22 series but that wouldn't 
work as well. I contacted Alan Cox and he made some patches/suggestions
that made 2.6.22-git16 with libata work!
I hope his patch will make it into mainline soon.

For the dmesg output of this kernel

I will certainly will read/try that.

i booted with routeirq=pci but gave the same negative result.

kernel configs are also in above mentioned webdir

basically copied the 2.6.22-git17 and ran a make oldconfig.


Did a diff -u on those config files and there is really a lot different:

[snip]
-# ATA/IDE/MFM/RLL support
+# Device Drivers
 #
[snip]
 #
 # IDE chipset support/bugfixes
 #
+# CONFIG_BLK_DEV_TRM290 is not set
 CONFIG_BLK_DEV_VIA82CXXX=y
-# CONFIG_IDE_CHIPSETS is not set
-# CONFIG_IDEDMA_AUTO is not set
+# CONFIG_BLK_DEV_TC86C001 is not set
+# CONFIG_IDE_ARM is not set
+CONFIG_BLK_DEV_IDEDMA=y
 # CONFIG_IDEDMA_IVB is not set
-# CONFIG_DMA_NONPCI is not set


I will run a make menuconfig and see if i can clean things up.

Thanks for your feedback/enthousiasm!
