There is a problem with the detection of the pdcraid-hardware when using the 1.4_rc1 release. 1.2 release works fine. Below I have posted a summary. If more testing or providing information is required please let me know. -involved hardware: pdcraid (pdc20276) -image with problem: livecd-ut2003-x86-1.4_rc1-r1.iso and livecd-basic-1.4_rc1-r2.iso (both MD5 checked and correct) -image without problem: gentoo-i686-1.2.iso -result "insmod ataraid": using /lib/modules/2.4.19-xfs-r1/kernel/drivers/ide/ataraid.o -result "insmod pdcraid": using /lib/modules/2.4.19-xfs-r1/kernel/drivers/ide/pdcraid.o /lib/modules/2.4.19-xfs-r1/kernel/drivers/ide/pdcraid.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or at the output from dmesg -result "dmesg": Promise Fasttrak(tm) Softwareraid driver 0.03beta: No raid arry found -scope: I saw on the forums that more people have problems when using the 1.4_rc1(-r2) release and not with the 1.2 release.
This is probably due to a really stupid bug. There's an #ifdef and an #ifndef that are backwards in ide-pci.c. If CONFIG_PDC202XX_FORCE is set, then everything works backwards and the raid controller is NOT initialized. Applying this fix let me use pdcraid for my root device again, so it may be the fix needed here. Lines 405 and 672 need to be switched to the opposite case.
Created attachment 4194 [details, diff] Simple #ifdef/#ifndef patch for pdcraid
Adding Brandon to the CC-list, because this is related to the kernel. He might be interested in the patch.
Please try the latest 2002122100 livecd at http://www.gentoo.org/dyn/experimental/livecd/. We are using a 2.4.19- derivative; if this hasn't been fixed in it then we really need to roll in this patch soon. Thanks for the bug report.
I have tested the 2002122100 LiveCD, I have the same problem, the problem should be fixed with kernel 2.4.20. There are a few (3-4) fixes for pdcraid in 2.4.20. Please let me know if more testing is required. PS. I can't see the isolinux boot graphic, the screen is completely blue, do you want me to create a bug for this?
Yes, please create a new bug for this.
I have tested the 2002122300 LiveCD and I can confirm that pdcraid works perfectly.
Great :) I will now close this bug.
Moving these so we can remove the "Install CD" component from "Gentoo Linux". I apologize to everyone for this spam, but according to the bugzilla developers, this is the only reasonable way to do this.
