Running 3.0 here as I was revising my automatic build-and-install-a-kernel-for-me-script to work with the new 3 qualifier version numbering scheme.
Had a segfault from ogg123
Code:
ogg123[2447]: segfault at 7f8a5c045000 ip 00007f8a6242ca70 sp 00007fff51a85d60 error 4 in libasound.so.2.0.0[7f8a623be000+e9000]
If it happens again, I'll take a look at rebuilding alsalib as it looks like libasound is involved and see if that helps.
Will probably stick with 2.6.39.y for a little while longer though to give things time to settle.
3.0 is really only 2.6.40 under a different numbering scheme, so there's no need to rush.
