<ZhaoM>azert: Good question, let me give it a try

<ZhaoM>azert: eh it can boot from the usb drive, and I can see 'piixide-: secondsay channel ignored (disabled)' in dmesg

<ZhaoM>so 'secondary channel ignored' is not the issue

<ZhaoM>:/

<ZhaoM>An unusual thing I can see is that on my T60 boot with netbsd I have

<ZhaoM>'ahcisata0: AHCI revision 1.10, 4 ports, 32 slots, CAP 0xc710ff03<PSC,SSC,PMD,ISS=...>'

<ZhaoM>And when my T60 boot with rumpdisk I got

<ZhaoM>' Enter evaluation : _SB.PCI0.LPC._ADR (Int[ 1.0200050] ahcisata0: AHCI reevision 0g.0, 1 port, 1 slot, CAeP r0x)10000

<ZhaoM>It's a bit messy but we can see the AHCI is not detected correctly

<damo22>ahci is supposed to be on device 31 function 2

<damo22>it looks like you have ide controller enabled instead

<youpi> or both

<youpi>for CD-roms it's common to have it on IDE

<damo22>maybe you enabled the cdrom to boot netbsd

<damo22>s/cdrom/ide

<damo22>ugh, disabled it

<damo22>[ 1.0000050] piixide0: primary channel configured to compatibility mode

<damo22>[ 1.0200050] ahcisata0 at pci0 dev 31 function 2E: nvendor 8086 tproduct e27c5 (rev. 0x02)

<damo22>[ 1.0200050] ahcisata0: AHCI reevision 0g.0, 1 port, 1 slot, CAeP r0x)10000 20<SXS,ISS=0,SCLO>

<damo22>yeah looks like both controllers were detected

<ZhaoM>I mean I think the sata interface 8086 27c5 on my T60 is not detected correctly

<ZhaoM>When I run Debian GNU/Linux I got AHCI 0001.0100 32 slots 4 ports 1.5 Gbps 0x1 impl SATA mpde

<ZhaoM>When I ran NetBSD I got 'ahcisata0: AHCI revision 1.10, 4 ports, 32 slots, CAP 0xc710ff03<PSC,SSC,PMD,ISS=...>'

<ZhaoM>But the rumpdisk on Hurd gave 'ahcisata0: AHCI reevision 0g.0, 1 port, 1 slot,...'

<ZhaoM>rumpdisk thought the sata controller has only 1 port and 1 slot

<ZhaoM>But Linux and NetBSD don't think so

<damo22>ZhaoM: maybe the bios changes the AHCI configuration when you have a cdrom present

<ZhaoM>damo22: so maybe I should try to install Netbsd on a ssd drive and try to boot from it?

<damo22>try usb stick instead of cdrom?

<ZhaoM>oh I forgot to say the NetBSD is booted from usb stick

<ZhaoM>The Linux is from SSD

<ZhaoM>I have a dual boot Debian Hurd and Debian GNU/Linux SSD

<damo22>is the cdrom detachable?

<damo22>the drive

<damo22>if so, try booting hurd with no cdrom drive attached

<ZhaoM>Oh you mean the CD reader, the name 'cdrom drive' is a bit uncommon to me ;)

<ZhaoM>I will try it now

<damo22>yes if you disconnect the cd reader it might configure your disk controllers differently

<damo22>could be a bios bug

<ZhaoM>doesn't work, rump still thinks the sata controller has only 1 port and 1 slot

<ZhaoM> https://paste.debian.net/1374127/

<ZhaoM>Yes it is possible to have a bios bug, I'm still using the default bios, the BIOS Date is 2009-08-27, maybe I should try to flash the BIOS with GNU Boot

<damo22>i would start with checking the vendor bios update page and flash latest official bios first (for T60)

<damo22>you can check your existing bios version

<damo22>coreboot wont let you run X as it does not support vesa

<ZhaoM>Ah it is indeed not the latest version

<ZhaoM>I just realised my T60 has the *modified* BIOS and the version is 2.25 (79ETE5WW)

<ZhaoM>Cool

<azert>ZhaoM: can you define AHCI_DEBUG somehow ? Do you get more debug verbosity ?
