Distribution: Gentoo Hardware Environment: PIII SMP, ACPI, EMU10K1, fglrx Software Environment: Xfree86 Problem Description: My mouse will freeze randomnly in X. However, everything still operates fine using the keybord. If I switch to a VT, attempt to reboot X, or logout of my session, the computer seems to crash. At this point ctrl+alt+delete does nothing and I just have a black screen. If I press my power button it does shut-down safely though. (This is the only way I've found to shut down at this point without a hard reset) This power button feature works because of ACPI and the acpid daemon I have running. (This may be indicative of something, I'm not sure) The problem does seem to be related to ALSA in some ways. Ocassionally IRQ 18 is disabled along with 10. (18 is EMU10K1). Often the error occurs immediately when I click the next button in xmms or when I'm using other programs that make use of ALSA. I have posted this bug to the gentoo forum and received a lot of response from people with an almost identical problem. Many found that disabling ACPI fixed the problem. Also it was found that this bug has entered into the kernel around 2.6.3 See: http://forums.gentoo.org/viewtopic.php?p=1050753#1050753
