Check that the last line of trapinit(), > /sys/src/fs/pc/trap.c:192 in my copy, is: > > fpinit(); I don't even make it to the fs kernel, I'm already hanging in 9load. My copy of /sys/src/boot/pc/trap.c is up to date with sources; however, comparing that with sys/src/fs/pc/trap.c I do see some differences. i tried to integrate those differences, but failed to solve the problem (the resulting 9load was able to boot a kernel on another machine) Then, I tried 'shuffling' and disabling hardware, with more success!!! `plain' 9load works, except when a usb keyboard is attached to usb2 (disconnecting the usb keyboard, or connecting to a (sufficiently) different usb port is sufficient to make 9load work again. plugging it back into the original port makes it fail again) why 9load stopped working when I changed agp card I don't know, I suppose because interrupts moved, don't know the 'original' irq assignment. Some details in case anyone is interested: The motherboard is a shuttle ak32vn (via kt266a + vt8235) when keyboard is on usb2 (irq 10) 9load gets stuck term% cat /dev/irqalloc 3 0 debugpt 7 0 mathemu 8 0 doublefault 9 0 mathover 14 0 fault386 15 0 unexpected 16 0 matherror 32 0 clock 33 1 kbd 35 3 usb1 36 4 COM1 38 6 floppy 39 7 lpt 42 10 usb2 43 11 usb0 43 11 ether0 44 12 kbdaux 46 14 sdC (ata) 47 15 sdD (ata) term% pci 0.0.0: 06.00.00 1106/3099 0 0.1.0: 06.04.00 1106/b099 0 0.10.0: 04.80.00 1131/7134 10 0:ef000000 1024 0.12.0: 02.00.00 10b7/9001 11 0:0000d001 64 0.16.0: 0c.03.00 1106/3038 11 4:0000d401 32 0.16.1: 0c.03.00 1106/3038 3 4:0000d801 32 0.16.2: 0c.03.00 1106/3038 10 4:0000dc01 32 0.16.3: 0c.03.20 1106/3104 5 0:ef001000 256 0.17.0: 06.01.00 1106/3177 0 0.17.1: 01.01.8a 1106/0571 255 4:0000e001 16 0.17.5: 04.01.00 1106/3059 10 0:0000e401 256 1.0.0: 03.00.00 10de/0110 11 0:ec000000 16777216 1:e0000008 134217728 term% Axel. - glad that it works now
