I have a ASrock P4I45GV R 5.0 mainboard. It has instead of a normal AGP slot a so-called "AGI", which is, as much as I understand, some kind of an AGP emulation on a PCI slot. So, i've had some problems with Linux, meaning that I should compile the kernel and turn off from there the APIC option. I usually did like this: I changed from BIOS the videocard from AGI to internal one, booted the installed linux with it, compiled a new kernel and after that booted using the AGP-standart videocard. But, in Gentoo, this doesn't work. During kernel compilation i get a message that the root filesystem is (3,1). And when i boot it, even if in grub.conf is specified the root=/dev/hda1 line, it boots from there. But i found a work-around: I installed Debian, booted from it, compiled the vanilla 2-6-28-2 kernel from it, copied it, the System.map and modules to their places, and it works, but only for the included videocard Reproducible: Always Steps to Reproduce: 1.On a ASROCK P4I45GV mainboard, compile the kernel 2.Boot from it. 3. Actual Results: List of all partititions: 0300 78184008 hda driver:ide-disk 0301 5735173 hda1 0302 1 hda2 0340 811446 hdb driver: ide-cdrom No filesystem could mount root, tried: reiserfs ext3 ext2 cramfs msdos vfat iso9660 Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(3,1). Expected Results: it should have booted the system

Please explain how this bug report can improve Gentoo Linux.
(In reply to comment #4) > Please explain how this bug report can improve Gentoo Linux. > Well, I think that this bug is tied to some recent changes made in Gentoo environment. Thet's because in Debian the kernel booted with the AGP videocard, but under Gentoo it works only with the included one. In fact, it wouldn't bring Gentoo nothing, except the possibility to discover some new bugs in it. I'm not an IT professional, so that I could tell you what is wrong with it. But a month ago, Gentoo worked fine with my card. Now it doesn't.
Sorry, that's not enough. Please reopen this bug report after you have added full details, maybe a reference to an upstream bug report, some error messages and so on.
