( disclaimer : This is the first time I follow current, i have no
experience debugging kernels, but willing to figure out why this box
wont take FBSD).
I have a server wich is generating panics as soon as the kernel tries to
load (as soon as the bootloader finishes), same sitatuation under 5.4
installer + normal boot, and 4.11 installer - pls see :
(After some more checks, it seems Gentoo 5.0 universal boots up, but has
trouble seeing the drives)
So I decided to give 6.0 Beta 2 a try. It panic'ed in the same
spot...falls into the debugger. Then if I type 'next' it boots up and I
can install as normal (1 drive only, not using the RAID controller yet).
Same happens on bootup from disk.
I copied the following by hand:
[boot command prompt]
/boot/kernel/kernel text-0481944 data=0x80de4+...
[[[changes to bright text...PANIC]]]
GDB: no debug ports present
KDB: debugger backends: ddb
KDB: current backend: ddb

[[[here it boots up fine - i can see several 'error reading from 0xf843'
errors, where the address 0xf843 increments, but I can't catch what it
said - i can try again if it's important]]]]
Thanks a lot in advance,
