Subject: Interrupt conflicts with Debian on Lib U100
Hi All,
I wonder if anyone else has run into interrupt conflict issues on the
U100 with Linux (Debian Etch 2.6.12 in my case). I have had a look
around and this problem seems to some up with several Toshiba Laptops,
but I haven't found a satisfactory solution.
The curious thing is that I have no problems when hard booting. But
if I soft reboot, IRQ 11 goes down, taking ethernet, wireless,
firewire and USB 2 with it.
I have looked at the BIOS, and it looks like you can't change the IRQ
assignment of the PCI Bus.
If anyone has come across (and hopefully fixed!) this problem, I'd
love to hear from you.
regards,
Jon
