2006-12-20 (Wednesday) still crashes, perhaps a bit further on: Vector 700, eventual sig: 5. Will attach photo of VGA console. Created attachment 144112 [details]

Still happens with kernel-2.6.19-1.2906.fc7 on today's rescue CD (2007-01-09). The traceback shows the same subroutines, although the addresses have moved a little. There was a memory corruption bug which affected all architectures -- allocating only a single page when more than that was requested. The ide-pmac driver has an allocation of 0x1020 bytes, which showed this error quite nicely. It looks like that's what you were seeing. It's fixed now -- please try again. Fixed in the PowerPC rescue CD-ROM of 2007-03-26 with sha1sum: 62fd25c4279260e28448aa4ece5737f43e4ce9f7 FC-development-ppc-rescuecd.iso "boot: linux" gets at least as far as choosing language, keyboard, install method, dhcp+ipv4, no ipv6, mirror, directory, etc. |
Description of problem: crash during boot Version-Release number of selected component (if applicable): kernel-2.6.19-1.2885.fc7 How reproducible: always Steps to Reproduce: 1. "boot: linux" using the 2006-12-19 (Tuesday) rescue CD for PowerPC 2. 3. Actual results: Eventual 3 minute loop with: Unable to handle kernel paging request for data at address 0x0 Faulting instruction address: 0xc0126659 Oops: Kernel access of bad area, sig: 11 [#1] <traceback omitted> but there was an earlier message that did not stop: Vector: 300 (Data Access) at [dffc3d20] pc: c0126658: list_del+0x14/0x88 lr: c008ec49: cache_alloc_refill+0x178/0x55c sp: dffc3dd0 msr: 1032 just before "hdb: Enabling Ultra DMA2". Expected results: successful boot Additional info: I will attach photo of console, but some interesting lines probably scrolled off the top when the "Vector: 300..." did not pause. Hardware is Apple Macintosh mini PowerPC 32-bit.
