-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi,
> > BUG: soft lockup - CPU#0 stuck for 22s! [irq-17:0002] > > Please send the log messages that appear immediately after this. There are no messages after this. The I/O part of the kernel goes into a deadlock and the system becomes unresponsible. I can move the mouse and click around in XFCE, but opening menues and everything that would require disk access fails and freezes the process requesting it. > > I haven't really figured out how to reproduce it but it does lead to data > > loss. > [...] > > I don't think we would class this as 'data loss'. See > <http://kernel-handbook.alioth.debian.org/ch-bugs.html#s9.1.2>. As it freezes the entire I/O, there is risk of data loss. In fact, it corrupted one of my git repositories on disk because some cached writes didn't sync. I tried to open a text editor and save the error message (the one I psoted above), but I couldn't start up the editor. I then used my shell's built-in cat to store the message in a file, the file appeared in the filesystem, but never got written to the disk. I could not even trigger an emergency sync via SysRq. It just didn't happen. Once the b43 driver goes into the freeze, the whoe kernel fails to do any I/O. I, personally, consider this as a risk of data loss. - -- * mirabilos is handling my post-1990 smartphone * <mirabilos> Aaah, it vibrates! Wherefor art thou, daemonic device??
