Re: reiser4 bug in 2.6.16-rc2-mm1

[John Cohorn]

Is there a known issue with 2.6.16-xxx-mm1? I too am having severe and very random, but reproducible problems which will completely lock up my machine minutes after mounting an R4 partition if not seconds. I did try disabling 4K stacks in my .config. Also, this is an Athlon 64 X2 I'm running with so maybe there are SMP issues? One of my friends said that Reiser4 became unstable for him also when he upgraded to a dual core Athlon64...but until I test for myself that's just a wild theory that it's an SMP bug. This machine is otherwise stable in Memtest, in Windows playing the latest games, and on Linux compiling huge amounts of software.

If there are not known issues with the latest kernels then I will happily try to send detailed configurations and logs of what's happening this evening. I have two shiny new 250GB SATA drives on my machine and I can test freely with one of them until I need the space. I'd love to help squash any bugs that I can :)
