Great, thanks. I'll try out the depth fix tonight. -- Nick Bowler, Elliptic Technologies (http://www.elliptictech.com/) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

As upstream doesn't consider the first to be a kernel issue, I guess you should just list the second.

OK, if the failure is due to userspace is doing Very Bad Things(tm), catching that seems reasonable. Nevertheless, even if it happened by luck, the result was (ostensibly) working programs that suddenly break once one "upgrades" to the latest kernel. If userspace can't be fixed before 2.6.34 is released, perhaps a less cryptic log message would be appropriate? -- Nick Bowler, Elliptic Technologies (http://www.elliptictech.com/) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
