This made me think of a blog entry by DaveM from some time ago: http://vger.kernel.org/~davem/cgi-bin/blog.cgi/2006/06/09 > Another problem has been reported related to libtorrent: according to > http://bugs.debian.org/402707 someone also saw this with non-Debian > 2.6.19 but obviously it's hard to say whether the bugs are really > related. > http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=394392;msg=24 shows > some dmesg messages but again it's not 100% clear it's the same bug. > > Has anyone else seen problems or is aware of a fix to the patches > listed above that I'm unaware of?

What is not clear from all these reports is what architectures this is seen on. I suspect some of them are i686, which together with the explicit mention of ARM make it a cross platform issue. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
