After installing this new wonder kernel on my AMD-64 laptop, I discovered that Beagle wouldn't start. While enjoying how fast my system felt ( :) ) I also discovered that Evolution wouldn't start because it was built with mono integration.
Can't live without email, so I poked at it and discovered that if I run mono applications (including Evolution) with the legacy memory layout, they work.
Like this: setarch x86_64 -L evolution
This didn't happen on -rc2-mm2, so I think somebody changed something. Mono claims to mmap with the MAP_32BIT option.
In -rc3-mm1 strace shows mono's mmap like this: mmap(NULL, 65536, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANONYMOUS|MAP_32BIT, -1, 0) = 0x7fa21f5cb000
It's got MAP_32BIT, but that's not a 32-bit address... -- Zan Lynx <zlynx@acm.org> [unhandled content-type:application/pgp-signature] |
