Just a side note, the desktop on which the problem (still) occurs follow
the RELENG_5 branch and the build used at this time is as follow:
FreeBSD 5.3-STABLE #0: Fri Feb 4 05:38:57 CET 2005
But since mid/end-december 2004 (for ~2 months now _approximatively_) i
encountered systematically an interrupt storm from the USB host controller
which prevent me inevitably to be able to use all of ly USB devices:
Interrupt storm detected on "irq10: uhci0 uhci1+"; throttling interrupt
source
In this context, if i reenable ACPI support on boot, i didn't see any
interrupt storm problem anymore... but i still can't use USB on this
system.
So, i now had an unusable USB system:
- ACPI disable / uhci interrupt storm (doesn't even get the device
created on the fly) => unusable USB devices
- ACPI enable / "conflict" with USB stack (doesn't even get the device
created on the fly) => unusable USB devices
Any advice?
