Tiny Core Base > Release Candidate Testing
Core v16.0beta1
CNK:
I tested TC16 on a desktop PC with an AM486DX2-66 and 20MB of RAM. The system reboots at the same point when the kernel should start. TC15 boots fine (in under 40 seconds with my stripped-down tc-config) and doesn't even use the swap space.
I'll see if I can find some bigger RAM sticks to increase the RAM more significantly above 16MB (might take a while, RAM was even more poorly labeled in those days) in case the TC16 kernel needs way more for some reason. But I'm more convinced that it's a processor compatibility problem with the new kernel.
Will test on the HP 2533t too once I sort out how to get TC16 onto it. Some of the features I've tried disabling on the kernel command line for the 486 might be worth trying with that as well:
--- Code: ---highres=off mitigations=off nosmp nosmt acpi=off
--- End code ---

Thanks, Rich. That makes sense.
FWIW, I've been doing all my fluff testing on Core 16.0beta1 / x86_64 and the RC seems rock solid on my laptop. I haven't been back to 15.0 since 16.0apha1 was posted except for once when I wanted to verify something. (mind you, I have backups, just in case.)

Regardless of those options the boot process hangs on my HP 2533t with the standard TC16 kernel. It always hangs either immediately after the "run /sbin/init" message, or at some random point during tc-config. The vmlinuz-6.12.11-printkdelay kernel boots fine. Tried booting from USB and from its PATA flash drive with all peripherals disabled in the BIOS, but same issue with the standard TC16 kernel.
It's curious that the standard kernel never hangs before the init process is started. I wonder if it's something to do with the task scheduler? I'll try some scheduler-related kernel boot commands when I get the time/energy.
Dmesg shows a message suggesting that "tsc=unstable" be added to the kernel command line (in TC15 and TC16), but adding that doesn't help the TC16 kernel boot. Maybe use "clocksource=hpet" instead of default "clocksource=tsc"? No time to dig deeper, I should be working now...
