Hi, on my laptop, I am a heavy user of laptop-mode and suspend-to-disk. Sometimes (maybe once out of ten), when disconnecting or connecting external power, I have a mount process called by laptopmode busy looping and taking all available CPU: ├─acpid,4680 -c /etc/acpi/events │ └─lm_ac_adapter.s,29317 /etc/acpi/actions/lm_ac_adapter.sh │ └─laptop_mode,29318 /usr/sbin/laptop_mode auto │ └─laptop-mode,29386 /usr/share/laptop-mode-tools/modules/laptop-mode │ └─laptop-mode,29390 /usr/share/laptop-mode-tools/modules/laptop-mode │ └─laptop-mode,29409 /usr/share/laptop-mode-tools/modules/laptop-mode │ └─mount,29410 /dev/mapper/usr /mnt/usr -t ext3 -o remount,rw,commit=600 this is what top says Cpu(s): 2.7%us, 96.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 1.3%hi, 0.0%si, 0.0%st 29410 root 20 0 2068 684 564 R 92.7 0.0 87:37.71 mount The mount process does not react to SIGKILL, stracing the looping process doesn't give any output, and the strace gets stuck and does not react to Ctrl-C. A SIGKILL works for the strace process, though. To me as a layman this looks like the mount process gets stuck somewhere in kernel land. I currently have the issue with 2.6.26.3. In the situation of plugging and/or unplugging the power, the notebook used to completely freeze in the time when 2.6.24 and 2.6.25.$SMALL were in use, with 2.6.25.$HIGH and 2.6.26 I haven't hat these freezes any more. However, I am now plagued with the hanging mount processes. Any ideas?
