Message-ID: <20000910224951.G10171@hectic.net> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-embedded@lists.linuxppc.org List-Id: Hi, I can't seem to find the problem with the init not working on the Sandpoint. Here are some more details. In a nutshell, when the kernel gets to the point of running init, it gets stuck. The console works, and it responds to pings, but it doesn't proceed running init. Usually. Once, it did run init for me (that actually was sash). I didn't do anything different that time so I don't know how that happened. In any case, it crashed after a minute of work, when I did the following: bash-2.03# cat tty/driver NIP: C0032854 XER: 20000000 LR: C00327E0 REGS: c1e23d60 TRAP: 0600 MSR: 00009032 EE: 1 PR: 0 FP: 0 ME: 1 IR/DR: 11 TASK = c1e22000[41] 'cat' Last syscall: 5 last math c1e22000 last altivec 00000000 GPR00: BD3D2722 C1E23E10 C1E22000 C013D760 00000000 00000000 C013D7BC 0C44D0B7 GPR08: C0140000 BD3D2712 00000000 00000000 84262422 0184A4DC 00000000 00000000 GPR16: 00000001 7FFFFE54 7FFFFD30 00000002 00009032 01E23E80 00000000 C0004F1C GPR24: C0004C6C 00000000 00001000 FFFFFFE9 C1E69B80 C02EBDE0 C1DFE400 C013D760 Call backtrace: C00327E0 C00327AC C0032BB8 C0004CC0 01800724 018014AC 0170C75C 00000000 Kernel panic: kernel access of bad area pc c0032854 lr c00327e0 address BD3D2721 Rebooting in 180 seconds.. Another time, it died right after (or during) mounting the NFS filesystem: NIP: C005F72C XER: 20000000 LR: C00CA164 REGS: c02e3d00 TRAP: 0300 MSR: 00009032 EE: 1 PR: 0 FP: 0 ME: 1 IR/DR: 11 TASK = c02e2000[5] 'rpciod' Last syscall: 36 last math 00000000 last altivec 00000000 GPR00: C00CA164 C02E3DB0 C02E2000 00000001 C02F7A6C C0136F48 C01141C0 00000000 GPR08: 00000000 00000000 C0177320 00000000 0D860800 00000000 00000000 00000000 GPR16: C02E81C0 C02E814C 00000000 00000000 C02F7A68 C0100000 C0140000 C01023E0 GPR24: C0100000 C01145F0 C0110000 C0110000 C02E814C C005F6E0 C0136F48 00000000 Call backtrace: C02E3E60 C00CA164 C00CD87C C00CDE88 C00CE96C C00094FC Kernel panic: kernel access of bad area pc c005f72c lr c00ca164 address 20 tsk 5 Rebooting in 180 seconds.. I think there were a few more crashes like this, during different stages of trying to run init.. Usually in different places, but always with the message "kernel access of bad area". I don't have the backtraces here, but they were prefectly normal, and since crashes always happened to me at different places, I suppose it's not very important. What does this "bad area" thing mean? How do we get rid of it? -- Alex Shnitman | http://www.debian.org alexsh@hectic.net, alexsh@linux.org.il +----------------------- http://alexsh.hectic.net UIN 188956 PGP key on web page E1 F2 7B 6C A0 31 80 28 63 B8 02 BA 65 C7 8B BA ** Sent via the linuxppc-embedded mail list.
