Hello
I upgrade a Cyrix 166 with a Xircom Portgear PCI USB card.
# lspci -v gives
00:0e.0 USB Controller: OPTi Inc. 82C861 (rev 10) (prog-if 10 [OHCI])
Subsystem: OPTi Inc.: Unknow device c861
Flags: bus master, medium devsel, latency 32, IRQ 11
Memory at e1410000 (32-bit, non prefetchable)
It doesn't seem that there is shared IRQ problems or IO conflict.
But, when I load usb-ohci module, computer freeze.
I put the driver
in the kernel (not module) with DEBUG flag and the dbg message included,
the kernel freezes after the following message:
...
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-ohci.c: USB OHCI at membase 0xc2802000 Irq 11
usb-ohci.c: usb-00:0e.0 OPTi Inc 82C861
usb.c: new USB bus registered, assigned number 1
I put printk instructions in the module, the usb-ohci freeze during
writel instructions line 2027:
writel(0x628,&ohci->regs->fminterval);
which is called with argument ohci->regs->fminterval = 0xc2826034
At the execution of this line, the computer freeze.
There is no USB controller on the mother board and I have disabled the
USB Controller initialisation (?) in the BIOS (ROM PCI/ISA BIOS 2A5IIC39
Award).
(Rq: Enable this option doesn't change anything)
Can you help me. Thanks for any suggestion and for the work you do and
sorry for people receiving this message twice.
