Hi there, ( 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 : http://lists.freebsd.org/pipermail/freebsd-questions/2005-July/094134.html and http://lists.freebsd.org/pipermail/freebsd-stable/2005-July/017291.html (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] OK: unload OK: boot /boot/kernel/kernel text-0481944 data=0x80de4+... /boot/kernel/acpi.ko ... [[[changes to bright text...PANIC]]] GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb [Thread pid 0 tid 0] Stopped at 0xf842: *** error readign from address f842 *** db> tr Tracing pid 0 tid 0 td 0x6091d620 (null)(f000e2c3,f000eef3,f000ff54,f0002b2e) at 0xf842 *** error reading from address f000eef7 *** db> s [thread pid 0 tid 0] Stopped at 0xf843: *** error reading from0xf843 *** db> p f843 db> next [[[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, Beto
