The PPC livecd for 1.4 rc6 consistently hangs when starting to process the SCSI driver boot code. I have no SCSI devices. My DVD/CD-ROM drive (hdc) gets detected. If I don't specify any boot parameters related to hdc, the kernel hangs after printing a line that looks like this: mesh: <something> synchronous 5 MB/s If I specify "live hdc=scsi-ide", I get slightly further but still hang after details of hdc are listed by the scsi driver. I believe this is a known bug on SMP PowerMac hardware that has been corrected by the SCSI/Mesh driver writer in the 2.4.20 kernel. Could we get a livecd with a newer kernel? Also, my IDE HD does not appear to get autodetected by the kernel as it boots. Specifying "live hda=1,1,1" at the boot prompt causes the kernel to print something about bad partition info and looks like it's not able to read the IDE drive. This also sounds like issues that have been resolved with newer kernels. Reproducible: Always Steps to Reproduce: 1.boot livecd on a dual processor G4 PowerMac3 (mirrored drive bay doors) with IDE harddisk and IDE DVD/CD R/W drive. 2.wait until kernel appears to halt on SCSI driver boot code. Actual Results: Just wait. It won't go any further as it hangs. Expected Results: The kernel should have booted to the gentoo livecd shell. The hardware I am running came out in November 2002 (Dual 1.25 GHz PPC, 1 GB ram, 120 MB IDE harddrive, combo DVD-RW,CD-RW drive).
Feel free to email me at tfiala@austin.rr.com. I'd be happy to try new ISO test images and to work on this from my end with any suggestions. Thanks!
new livecd(s) comming up asap 2.4.20-benh9 (could be 10 not sure) is used on _rc6 any suggestions on what kernel to use best?
Hmm, the behavior I'm seeing matches some bug fixes applied to the 2.4.19 kernel so I assumed the livecd for 1.4 rc6 was an older kernel. If there's any chance I could get a livecd without the built-in scsi support I can probably get past this and fiddle with different kernel building parameters to identify the exact problem. If you can find the exact kernel used on the ppc livecd, I'll look into it more and see if there's any applicable patches that could be used. Thanks!
More info: I've tried the 1.4rc5 livecd. I get more autodetection working. The kernel now picks up the ide2 bus (Apple UniNorth ATA-6 controller to which my hard disk is attached) and picks up the Sun GEM built-in 10/100/1000 BaseT ethernet controller. The rc6 disc picks up neither of these. If I pass in no kernel args to the rc5 disc, I get stuck after this line: mesh: configured for synchronous 5 MB/s If I pass in boot paramter "hdc=ide-scsi", I get a little further: mesh: configured for synchronous 5 MB/s Attached SCSI CD-ROM sr0 at scsi0, channel 0, ide 0, lun 0 sr0: scsi3-mmc drive: 24x/24x writer cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.12 That's the last thing I see before the kernel hangs. Is there any chance you could build me an iso for a livecd with minimal options (no scsi cdrom emulation)? I'm not sure that's the problem, but it seems the SCSI support is what is halting me. Here's all I need in the kernel: single-processor support Apple UniNorth ATA-6 ide controller support Apple KeyLargo ATA-4/3 ide controller support USB full HID support Sun GEM PCI 10/100/1000 Base T ethernet support Apple Airport wireless support (this one is optional, I can move my computer if necessary so I don't need the wireless) Please see the PowerPC Gentoo Forum and the topic "1.2r1 no ethernet; 1.4r6 no mesh lockup" for more info. This is my forum post soliciting help. Thank you very much for any help. I'll be happy to help out in any way I can. If you want to keep throwing different kernel configurations out to me on tiny iso images until we find one that boots all the way through, I'm good with that --- you don't need to build the full livecd until we can find a kernel configuration that boots. BTW, I've turned off multi-processor support --- I'm now running uni-processor (verified in OS X Get Info page). Thanks!
New rc7 livecd (based on kernel 2.4.21) up in a day or so. I hope the new kernel fixes the problem.
Can you try again with rc7 livecd and reopen this bug if necessary?
