fetchmail is an example of application, which was started, after the filesystem went faulty...
You might do: # dmesg -c then attach the output of: # echo w > /proc/sysrq-trigger" # dmesg compiled kernel with magic sysrq and waiting for reoccurrence... timeline: switched to ext4 happened once happened twice (wrote this entry) waiting... hmm...it doesnt occured again...and i switched to 2.6.28.7...so i close this bug... f**k, it just happened again...attached echo w > /proc/sysrq-trigger... ...if this happens, can i remove the blocker, so i can cleanly shutdown?

echo w > /proc/sysrq_trigger
This is probably fixed by: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2acf2c261b823d9d9ed954f348b97620297a36b5 which may make it to .28.y eventually... seems to be fixed...mentioned patch is in 2.6.28.9... |
