panic at boot

[ghaerr]

Hello @sparky4,

Can you by chance post a screenshot of the boot? That would help me determine more as to exactly what is happening.

Are you compiling this from scratch with a custom .config? Perhaps try cp ibmpc-1440.config .config and make clean; make, or download a binary image from the v0.7.0 release page. We can then determine if the reason is something under current development or not.

Thank you!

okay will do

custom

[sparky4]

it worked with defaults

it was the 8.0 dev version

Hello @sparky4,

The boot problem is that, for some reason, your system is trying to use CONFIG_BLK_DEV_FD, the new DF ('Direct to hw floppy support') driver, and the system isn't configured for CONFIG_ASYNCIO ('Use Async I/O in kernel'). This is shown by the line "root device 0400" but only "1 request hdrs".

The boot should default to using the BIOS disk driver (root device 0320) unless /bootopts has been modified with the line root=df0. Is that present on your system?

To fix this, either unset CONFIG_BLK_DEV_FD to remove the DF driver, or set CONFIG_ASYNCIO to enable async kernel I/O.

I will likely make a change that disallows including the DF driver when async I/O is not enabled so this isn't possible in the future.

Was there a particular approach you took to your custom system configuration?

Thank you!

no not really. and thank you! <3

@sparky4, can you please zip up and post your .config file? I will use that to determine why the system tried to boot /dev/df0 (DF driver) rather than /dev/fd0 (BIOS driver).

Is your BIOS configure to boot from HD rather than floppy? That could possibly be a reason this occured when linked with DF driver, although "BIOS drive 0" indicates the BIOS will boot from floppy. Also, can you check that your /bootopts has the line root=df0 in it, not commented out?
