I've booted with the patched kernel in the following way:
- BIOS option for mouse support still off ;
- Kernel commandline: kernel /vmlinuz-2.6.12-6mib7test root=/dev/evms/lv_racine ro 3 usb-handoff devfs=nomount noquiet vga=791
- USB mouse plugged to what I believe to be the USB 2.0 controller (according to the motherboard manual)
First thing I notice at boot is that "mouse doesn't work".
cat /proc/interrupts shows : CPU0 0: 208937 IO-APIC-edge timer 1: 334 IO-APIC-edge i8042 2: 0 XT-PIC cascade 4: 464 IO-APIC-edge serial 7: 3 IO-APIC-edge parport0 14: 1321 IO-APIC-edge ide4 15: 1330 IO-APIC-edge ide5 18: 822 IO-APIC-level eth0, eth1 19: 14157 IO-APIC-level ide0, ide1, ide2, ide3, ehci_hcd:usb4 21: 33962 IO-APIC-level uhci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3 22: 0 IO-APIC-level VIA8233 NMI: 0 LOC: 208855 ERR: 0 MIS: 0
Looking at dmesg or /var/log/mesages shows a huge number of : Jul 12 19:36:58 totor kernel: uhci_hcd 0000:00:10.2: IRQ, status = 0 Jul 12 19:36:58 totor kernel: uhci_hcd 0000:00:10.0: IRQ, status = 0 Jul 12 19:36:58 totor kernel: uhci_hcd 0000:00:10.1: IRQ, status = 0 Jul 12 19:36:58 totor kernel: uhci_hcd 0000:00:10.2: IRQ, status = 0
(3043 similar lines...)
...immediately at startup, then it stops complaining
The interesting thing is that I unplugged my USB mouse at 19:45 -- nothing happened, and plugged it back at 19:45:40, while looking at a "tail -f /var/log/messages"
And see what happened in the attached copy of my /var/log/messages for this session...
Doesn't mean anything to me ;-) but I hope it will be of some help for you...
Cheers.
