The current kernel version for 'lenny' is 2.6.26 (with stable updates and other fixes). 2.6.31 is known to have a large number of regressions outstanding, which is why it is not in Debian yet. > I configured this Kernel with and=20 > .

IRQ sharing is normal on PCs without MSI support, but to see where that's happening you need to look at /proc/interrupts and not the BIOS setup program or wherever you got the above information from.

I would expect the standard kernel version for 'lenny' or the 2.6.30 kernel from 'sid' to be more stable. > What debug features should i disable ? No idea, you didn't even specify what you enabled...
