Re: "BUG: soft lockup" on A1200; was: Re: Updated installation images for Debian Ports 2019-04-20



Szymon,

please try adding 'initcall_debug' to the bootstrap options.

Cheers,

You did not mention how much RAM you have which is rather important
to know. And how fast is the 040 clocked?
Apollo 1240 with full 68040 clocked at 40MHz with (continuous block of)
64MB of RAM.
Can you please post all relevant information here so that we don't rely
on external sites?
Below a full dmesg while booting 4.19.0-5, which I extracted from
installation ISO's. Amiboot was started with -r pointing to the
cdrom/initrd.gz

Try passing "init=/bin/bash" on the kernel command line.
See above - no difference.

That's not a Debian kernel you are booting here. Where does this kernel
come from?
This particular was actually build in debootstrap environment following
the instruction found in https://www.subsecret.dk/wiki/Linux_on_Amiga

I hope I cleared any doubts.
