I just tried Epiphany (the browser, not the game) briefly and it also crashed on a problem page (ebay.ca), but I will investigate further. The crashes like this are usually due to unaligned memory accesses, which will cause a SEGFAULT/SIGBUS on sparc, but is tolerated on i386/amd64 platforms. I would not be surprised if that's a manifestation of the bug reported previously [0,1], which, as far as I can tell, is still not fixed upstream. I found that the most useful thing to do is to generate a core file by starting the program in the shell where the core file size is set to unlimited using 'ulimit -c unlimited', then trigger the crash. Given the core file and program executable, gdb should be able to tell where the crash occurs (even better if you have the binary unstripped or have the debugging symbols for it - for example, there is an iceweasel-dbg package in Debian, providing debugging symbols for iceweasel). It is usually fairly easy to tell from the backtrace why the unaligned access happened, usually things like raw memory accesses, for example trying to read a 4-byte word from a location which is not aligned on a 4-byte boundary. Even if it's hard to tell immediately what's wrong, at least it will make a useful bug report. I think the relevant bug(s) for iceweasel have already been reported. It might be worthwhile submitting a bug report for epiphany. I am not a programmer, so won't be able to make much of the core file myself, but I'll have a go at doing this whenever I get a chance. gavin, [0] http://bugs.debian.org/362170 [1] https://bugzilla.mozilla.org/show_bug.cgi?id=161826 -- The thing about words is that meanings can twist just like a snake, and if you want to find snakes look for them behind words that have changed their meaning. -- Terry Pratchett, Lords and Ladies Gavin Duley WWW: http://gpd.sdf-eu.org/ -- To UNSUBSCRIBE, email to debian-sparc-requ...@lists.debian.org with a subject of "unsubscribe".

BTS didn't yield any results. I find it odd though. Why would you want to run virtual machines on your small uniprocessor system but not on your big multi-CPU system? I also find it odd that there are SMP kernels at all now that smp_alternatives is used.

Thanks. I have been able to find some Etch kernels compiled with openvz and smp support. No idea if those will work under Lenny though. Question: If openvz is possible under sparc64, why doesn't Debian support this? It's supported on other archs. Even odder, why does Debian supply SMP and non-SMP kernels for sparc64 but only a non-SMP kernel for sparc64-vserver and no vserver-sparc64-smp? As I understand it now, using the vserver kernel supplied for sparc64 would mean that 3 of my 4 CPUs would do nothing since it's not an SMP kernel. -- Sander Marechal -- To UNSUBSCRIBE, email to debian-sparc-requ...@lists.debian.org with a subject of "unsubscribe".

Well, that cpuinfo up there lists four processors 1.6GHz each (convert the clock tick number from hexadecimal :) so you want SMP, and you actually already have it in that kernel, otherwise it wouldn't have printed the above information.

UltraSparc IIIi kernel and virtualisation
Hi all, Sun has donated a server to my FOSS project (www.officeshots.org). It has an UltraSparc IIIi processor and 8 GB of RAM. Below is the output of /proc/cpuinfo: cpu : TI UltraSparc IIIi (Jalapeno) fpu : UltraSparc IIIi integrated FPU prom: OBP 4.22.19 2006/09/06 23:41 type: sun4u ncpus probed: 4 ncpus active: 4 D$ parity tl1 : 0 I$ parity tl1 : 0 Cpu0ClkTck : 5ee3fe00 Cpu1ClkTck : 5ee3fe00 Cpu2ClkTck : 5ee3fe00 Cpu3ClkTck : 5ee3fe00 MMU Type: Cheetah+ State: CPU0: online CPU1: online CPU2: online CPU3: online I have two questions about how to best use this machine. First off, do I need an SMP kernel for this machine? cpuinfo only lists a single processor, but it does mention "CPU0-3 online". Wikipedia says that this processor is single-threaded. My second question is what technology I can best use to run virtual machines on this server. Many options are not available (like Xen or VirtualBox) because they are for x86 only. Others like QEMU and Linux-vserver are available but I don't know how well they would perform. I've heared that QEMU is quite slow unless you use the KQEMU kernel module and it looks like that's not available in sparc64. The second question is also related to the first. At the moment this machine runs Debian Lenny sparc64-smp. Aptitude has both SMP and non-SMP kernels available but all the vserver enabled kernels are non-SMP. Aptitude show sparc64, sparc64-smp and sparc64-vserver kernels but no sparc64-smp-vserver kernel. Any advice is greatly appreciated. -- Sander Marechal Lone Wolves Foundation http://www.jejik.com -- To UNSUBSCRIBE, email to debian-sparc-requ...@lists.debian.org with a subject of "unsubscribe".
