Description of problem: After booting up system, kacpi_notify is in D-state and stays in that state $ top -b -n 1 | awk '{if (NR <=7) print; else if ($8 == "D") {print; count++} } END {print "Total status D: "count}' top - 09:31:00 up 1 min, 2 users, load average: 2.63, 1.27, 0.48 Tasks: 206 total, 1 running, 205 sleeping, 0 stopped, 0 zombie Cpu(s): 11.0%us, 14.3%sy, 0.0%ni, 48.5%id, 25.9%wa, 0.0%hi, 0.3%si, 0.0%st Mem: 3797480k total, 604448k used, 3193032k free, 47000k buffers Swap: 5898236k total, 0k used, 5898236k free, 220480k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 23 root 20 0 0 0 0 D 0.0 0.0 0:00.00 kacpi_notify Also, unsure if it is related, system randomly hangs during the udev stage on boot. It happens about 1 out of every 5 boots. Version-Release number of selected component (if applicable): $ uname -r 2.6.35.10-74.fc14.x86_64 How reproducible: Every successful boot, kacpi_notify is in this state. The system hanging is somewhat reproducible, but requires a few boots. Steps to Reproduce: 1. 2. 3.

Can you do this: 1. Add 'sysrq_always_enabled ignore_loglevel' to the kernel boot options. 2. Press alt-sysrq-t and capture the output (it should go to the syslog.) 3. Attach the output to this bug report.
Created attachment 475424 [details] The output from alt+sysrq+t.
More information on the system hanging problem. Here is an error message I get if I wait long enough (maybe 5 minutes?) before powering the computer off and on again. Starting udev: udevd[522]L worker [595] unexpectedly returned with status 0x0100 udevd[522]: worker [595] failed while handling '/devices/pci0000:00/0000:00:13.0/usb5/5-1/5-1:1.3' udevd[522]: worker [629] unexpectedly returned with status 0x0100 udevd[522]: worker [629] failed while handling '/devices/virtual/wmi/95F24279-4D7B-4334-9387-ACCDC67EF61C' [ OK ] Setting hostname localhost: [ OK ] Then it doesn't do anything else.
Does blacklisting the hp-wmi module make any difference?
(In reply to comment #4) > Does blacklisting the hp-wmi module make any difference? That seems to have taken care of both issues.
syslog has helpfully dropped some of the output from alt+sysrq+t. Never mind. Can you install the pmtools package, run acpidump as root and attach the output?
