comment force re-negotiation of PCIe speed on Linux
thanks for the answer ! In fact, in the end it turned out that the PCI card had a problem with data transmission on the PCI bus and the manufacturer fixed it with a firmware upgrade.

comment force re-negotiation of PCIe speed on Linux
thanks for this information ! Unfortunately, in my case the speed reduction happens on only some of the hosts and it does not go back to full speed when we start using the device again...

I think this question should be migrated somewhere else such as quant.stackexchange.com

comment Did `sudo init 6` cause my file system to be corrupted?
where did the error appear, inside the virtual machine or on the host system ? And where did you run sudo init 6, on the virtual machine or on the host ?

comment I killed sshd but it's still running?
that's why I wonder whether after killing it it still has the same process id or not (see my comment above)

comment I killed sshd but it's still running?
but doesn't inetd just start the corresponding daemon when a connection is made to a given port ? i.e. would one see an sshd process before an actual connection is made ? (rather than just inetd listening on port 22 ?)

which flavour of Unix is this ? After the kill command, does it still have the same process id ?

comment Linux Programmable Controller
not sure whether anyone would want to fit Linux into 256 kilobytes flash memory... (see en.wikipedia.org/wiki/Arduino#Arduino_board_models). Not unsurprisingly, with 2 kilobytes RAM these microcontrollers don't have a memory management unit either...

comment Uptime and who -b are showing different times when the system was last booted on Linux
when you reboot again, does who -b still show the same date (2009-07-09 20:51) or does it change ? The manpage of my who suggests that it is using /var/run/utmp if no file is specified. Are the write permissions for this file reasonable (user root and group utmp on my system) ? Is /var full ?

comment getting error “Can't create transaction lock” with rpm
does the directory /mnt/fedRoot/var/lib/rpm exist ? in analogy to redhat.com/archives/rpm-list/2007-May/msg00046.html , what does rpm --root=/mnt/fedRoot -E '%{_rpmlock_path}' say ?

comment Is '-9' a flag to kill command?
@Faheem, you can always use 'absolute' process numbers with /bin/kill but not things like %1 (which refers to the first job in the list of backgrounded jobs known to the shell)

comment How to pipe the result of 'date' command to 'mv' command
One should emphasize that these are backticks around the date command, not ordinary single quotes.

@Faheem, I think it's because the built-in commands have access to more information, such as the history of started commands, which /bin/kill seems not to have. For example, kill %1 works for the built-in command but not with /bin/kill (although one could argue that in principle the shell could expand %1 to the corresponding process id).

you can always do builtin kill to ensure that the built-in command is executed. But I bet that you were running the built-in kill -l when you got the numeric values of the signals. Contrary to what I posted before, /bin/kill -l only gives me names, not numbers (and I didn't know that bash has a built-in kill command as well).

@Faheem, yes zsh has a builtin kill command. Looking through the corresponding section of man zshbuiltins it's however not clear how it differs from the procps kill command. Accidentally, I noticed that I can do sleep 1000 & and then kill %sleep which kills the sleep command I started (it kills the most recent one if there are multiple). /bin/kill %sleep does not work on the other hand. By the way, bash seems to have a builtin kill command as well, it just is not reported by which kill (one has to do type kill to reveal this).

thanks for the comment, I'updated the answer.

it turns out that I was running zsh's builtin kill command, not /bin/kill (which actually lists the numeric values as you say)
