8.0-RC2 on Rackmac3,1 - fatal kernel trap

I've been trying to boot the 8.0-RC2 iso on an Xserve G5. After the
loader screen I simply get a fatal kernel trap. --- snip --- fatal kernel trap: exception = 0x7 (program) srr0 = 0x0 srr1 = 0x83030 lr = 0x59bfa0 curthread = 0 panic: program trap Uptime: 1s --- snip --- Here's my hardware details Machine Name: Xserve G5 Machine Model: RackMac3,1 CPU Type: PowerPC G5 (3.0) Number Of CPUs: 2 CPU Speed: 2 GHz L2 Cache (per CPU): 512 KB Memory: 2 GB Bus Speed: 1 GHz Boot ROM Version: 5.1.7f1 Do you guys have any advice for me? I'll see if I can dig up an 8.0-RC1 disc and report the results later tonight. -jacob -- -jacob _______________________________________________ freebsd-ppc@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "freebsd-ppc-unsubscribe@..." |

I'm not sure what's going on with the release CDs -- you should get
farther than that. Full support for this hardware is currently only in -CURRENT, and missed the 8.0 release inclusion deadline. It should be in 8-stable immediately after the release, however. I can supply an install ISO for -CURRENT, if you are interested. But the CD should at least get you to complaints from the SATA controller, and the kernel certainly should not be jumping to a NULL address like it appears to be doing. Can you give some more details on your setup (i.e. serial or video console, did you boot by pressing 'C' or from the Open Firmware prompt, etc.), and maybe the full transcript of your boot attempt, with the snipped bits restored?

Yes, please, it it's not too much trouble I'd love a -CURRENT ppc iso.
My previous attempts were all made with a video console. I've tried booting with 'C' at power up as well as issuing 'boot cd:,\boot\loader cd:0' from the openfirmware prompt. Results are the same either way. I finally yanked it from our data center last night and brought it to the office where I can fiddle with it in comfort; I should be able to provide you with a full boot transcript sometime later today. -jacob On Nov 4, 2009, at 6:18 PM, Nathan Whitehorn <nwhitehorn@...> wrote: > I'm not sure what's going on with the release CDs -- you should get > farther than that.

All-righty, I've got three boot transcripts for you're viewing pleasure.
First, I snagged a copy of 8.0-CURRENT-200906-powerpc-disc1.iso and burned it. I've removed the ATI video card so this is all done from the serial console with Open Firmware.

I just took a look at the data layout in the kernel, and translations
immediately precedes ofwcall, so there is no question that the buffer size has been exceeded and that the zeroing the translations buffer has killed ofwcall. I'll send you a new CD with a larger buffer (and bounds checking) sometime at the beginning of next week. Hopefully, the change will also be merged in 8.0-RELEASE. -Nathan Nathan Whitehorn wrote: > This is the middle of reading out the current MMU translations from > Open Firmware (the OF_getprop() call at line 902 of mmu_oea64.c).

Almost :) My 7,2 and 11,2 G5's now hit the panic: 7,2: 120 translations 11,2: 126 translations If you are concerned about BSS usage for holding the translations, it might be possible to bump up the loader's unit of allocation from 16 pages to 64 when on a G5.

Also, it is now too late to get any changes to this code into 8.0, which is unfortunate. I guess the size of the buffer just needs to be bumped to 128 (or more?). I'm a little concerned about bloating the kernel here. I think there is enough headroom in the stack that it can be moved to the local stack frame, so that's a possibility. It can't be allocated dynamically, since there is no way to add memory that OF can use at that point in the boot process. -Nathan _______________________________________________ freebsd-ppc@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "freebsd-ppc-unsubscribe@..." |

It's due to a bunch of extra allocations needed for the md root fs image that is loaded pre-boot. The allocations can be seen by breaking into the loader just before boot and issuing a 'memmap'. Lots of 16-page allocations there. > I'm a little concerned about bloating the kernel here.

There's no elegant way to do it :( You could claim some pages from ofw to hold all of the mappings, or even pass off the work back to the loader and get it to put all of the mappings into metadata, or to at least pass some pages to you that could be used for the allocation. later, Peter. _______________________________________________ freebsd-ppc@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "freebsd-ppc-unsubscribe@..." |

Hello Peter, Nathan fellow PPC-owner
The link to the ISO file is very slow for me, downloads at 20 kB/s. In the meantime, I gave 8.0 rc3 a chance but I get the following: panic: moea64_bootstrap: too many ofw translations (100) uptime: 1s The boot process never came this far for me. The machine is a G5 PowerMac7,3, dual 2.3 GHz, 4GB ram. Is the 20091112 snapshot also ideal for my configuration ? Or is it safer to grab the 20091111 version ?

Either should boot your machine without problems. Unfortunately, due to this problem being discovered so late in the release cycle, the fix for CD booting will not make it into the 8.0 release. 8.0 will boot and run fine on G5 systems, but will have to be installed by net-booting. Once the 8.0 release is finalized, I will MFC the patches place an 8.0-STABLE-SNAP install CD somewhere for people who want it. -Nathan _______________________________________________ freebsd-ppc@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "freebsd-ppc-unsubscribe@..." |

Hmm, bad news.
The 20091112 ISO was used, if that matters. No extra configuration was taken, just hit the enter key when prompted so. The kernel does not correctly handle acd0. Here's the relevant log .... acd0: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - complete request directly acd0: TIMEOUT - READ_BIG retrying (1 retry left) acd0: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - complete request directly acd0: TIMEOUT - READ_BIG retrying (0 retries left) acd0: FAILURE - READ_BIG timed out This is repeated over and over.
