Hi This should be breeze for you hardware types. I'm wondering if this is of concern and how to fix the problem. I'm just finishing up an install of RH7.1 on a Dell Dimension somethingorother and am finding a *LOT* of lines in /var/log/messages that look like this: May 17 11:36:55 yggr kernel: usb-uhci.c: interrupt, status 3, frame# 1280 May 17 11:36:55 yggr kernel: usb-uhci.c: interrupt, status 3, frame# 1282 May 17 11:36:55 yggr kernel: usb-uhci.c: interrupt, status 3, frame# 1401 May 17 11:36:55 yggr kernel: usb-uhci.c: interrupt, status 3, frame# 1403 May 17 11:36:55 yggr kernel: usb-uhci.c: too many bad statuses May 17 11:50:00 yggr kernel: es1371: unloading May 17 11:50:00 yggr kernel: Uniform CD-ROM driver unloaded May 17 11:50:00 yggr kernel: hdc: ATAPI 48X CD-ROM drive, 128kB Cache, UDMA(33) /var/log/dmesg: usb.c: registered new driver usbdevfs usb.c: registered new driver hub usb-uhci.c: $Revision: 1.251 $ time 20:53:29 Apr 8 2001 usb-uhci.c: High bandwidth mode enabled PCI: Found IRQ 9 for device 00:07.2 PCI: The same IRQ used for device 00:10.0 usb-uhci.c: USB UHCI at I/O 0x1400, IRQ 9 usb-uhci.c: Detected 2 ports usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 2 ports detected hub.c: USB new device connect on bus1/2, assigned device number 2 usb.c: USB device 2 (vend/prod 0x3f0/0x107) is not claimed by any active driver. /proc/interrupts CPU0 0: 58912 XT-PIC timer 1: 713 XT-PIC keyboard 2: 0 XT-PIC cascade 8: 1 XT-PIC rtc 9: 16087 XT-PIC usb-uhci, es1371 <---??? 10: 6542 XT-PIC ide2 11: 12032 XT-PIC eth0 12: 21580 XT-PIC PS/2 Mouse 15: 3408 XT-PIC ide1 NMI: 0 ERR: 0 Eventually, the es1371 entry goes away. The way I see this, there is a conflict between the sound card and the USB port, and the USB eventually wins so the sound card gives up. Booting into winders98 (the original os), shows both of these devices on IRQ9, though they both claim no conflicts (Yeah, it's M$..., and when it boots into winders, the "boot sound" comes out a little choppy, so it would seem that something is wrong there). They are both automatically configured in winders. The Dell site really doesn't go into this too much, though I noticed a few errors in their description compared to what I've seen on the machine, so I'm not all that happy with what I read there either. Is this easily fixed? Not being much of a pc type, I'm really not sure how to go about it. Bios has none of this, just IRQ5 as reserved for legacy reasons, so it must've been set during the install.
