I've got a pretty repeatable problem here. This doesn't happen *every* attempt, but more likely than not:
Once I have used the video encoding or decoding functions of my iomega buz card, I cannot use the card again. If I do, the computer stops responding to keyboard and mouse input. I don't have another machine to try telnetting via a serial port, so I don't know if the machine is *really* locked up. But I know at least it won't respond to its own kbd & mouse! I suspect a problem with the zoran driver, but I'll go look elsewhere if somebody has seen this problem associated with other components. To repeat the problem, I can use lavrec (to record) or mplayer -vo zr (to playback) through the iomega buz. Here is how I repeated the problem this morning: Let's take lavrec as the example: >From a konsole window in kde, I typed: lavrec -fa -in -q5 -d2 -t90 /tmp/test.avi This runs for 90s and then exits back to a command prompt. Everythng appears to be OK. However, if I issue the same command again (with /tmp/test2.avi for the outfile this time), the computer locks up as described. Also, if I try to use xawtv to watch tv (under kde) instead of trying to record again, computer locks up as described. *After* rebooting (NOTE: MPlayer does not need to be run in order to cause the failure), I tried to play the avi file /tmp/test.avi with MPlayer. Plays just fine; looks great, sounds great. I've checked my irqs with cat /proc/interrupts, and no interrupts report shared. Before running lavrec, if I try to rmmod zoran, it removes just fine. But, after running lavrec, if I try to rmmod zoran, rmmod says "module in use". Actually, I made a "zoranreload" script that unloads all the zoran-specific modules in the right order and then says "modprobe zoran". Prior to running lavrec, I can do a clean unload/reload of all the modules just fine. Afterward, module "zoran" says it's "in use". But I'm not using it (I think??) What is causing these lockups? What can I do to fix the problem? I am writing this from my notes, trying to be thorough; if you want me to post output, say what tests you want me to run & I'll be very happy to do so. Thanks very much to anyone who can help me with this. Here's some relevant details: HW: mobo = Supermicro P6DBU (I440BX board) proc = dual PIII600 hw enabled on mobo: aic7xxx (irq10), usb (irq15). IDE turned OFF PCI cards: iomega buz (irq 5) in pci slot 2; soundblaster PCI (ES1370 chip) in pci slot 1 (irq 11--I think) ISA modem at com3--doesn't show up in cat /proc/interrupts Voodoo5/5500 in agp slot, using tdfx driver. No Framebuffer driver in modules or kernel. IRQs: Note again that cat /proc/interrupts doesn't show any shared IRQs. There is different info in the BIOS boot screen, but I don't really understand it. I can write it down and post it if you think I should. Environment - slack9beta current to 20Feb2003 linux-2.4.20 i2c-2.7.0 gcc-3.2.1 zorandriver-0.9.1 XFree 4.1.1 KDE-3.1 modules loaded (there's more modules, but these are the ones I think are relevant): i2c-core i2c-algo-bit saa7111 saa7185 zoran videocodec videodev (note, for some reason, when I modprobe zoran, all these load, BUT zr36060 doesn't load. Do I need to load it manually? Why doesn't modprobe zoran load it?)
