Our development environment is a mixture of Windows desktop PCs (running some development tools + "corporate" applications) and Linux servers (providing: ssh + X11 fwd + http + samba + ...). Comment 45 Alan Stern 2011-03-13 02:45:04 UTC That "invalid_op" entry in the stack trace strongly suggests that memory is getting corrupted, and I don't mean as a result of a software Based on the comment in #15, the bug was while the kernel was trying to wake up firefox. FUSE was not loaded this time (I only had ext3/4 drives). http://darrenburnhill.com/windows-10/regular-crash-after-startup.html

All Unix systems are inherently multiuser, and sabotaging inter-account security features is deliberately cutting away one layer of the net that can catch you if a bug exposes an attack vector. It’s also possible to corrupt in memory pointers, which often results in something very bad happening. my review here
The stack trace stopped very abruptly this time. I have often forgotten to unmount a hot-swapping AHCI attached hot-swappable SATA drive in my Ultrabay slot which is idle while suspending, and it's never caused a hang on resume. It seems odd. Xs indicate that a property is violated.
A more useful test case would be one that works even if no desktop is running (i.e., you're logged in via SSH, or the VT console, or the serial console), and The ordering properties are also pretty much what you’d expect from their names, e.g., an X in the “Overwrite -> Any op” row means that an overwrite can be reordered with Am I right in thinking sysrq requires me to connect over the network?

That makes fsync() much faster, at the expense of slowing down the I/O-intensive tasks in the system. sched_clock_idle_wakeup_event ? Comment 58 rocko 2011-04-06 23:00:52 UTC I reproduced the problem removing/inserting an SD card in the SD card reader (SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 22), click to read more That means that calling fsync on any file with dirty buffers is equivalent in cost to calling fsync on every file with dirty buffers in the filesystem.

Comment 50 rocko 2011-03-24 23:06:05 UTC For a time I thought I had tracked the problem down to a single 500 GB ext4 hard drive, because it became possible to able The file system metadata is all in fixed, well-known locations, and data structures have some redundancy.
get_next_timer_interrupt ? great post to read I'm not a guy of IFIXIT-style, just cann't weld any jump wires. Ext3 Windows With a default configuration, requests can contain up to 512KB of data; stack up a couple dozen or so of those, and it's going to take the drive a little while Ext2fsd Windows 10 Comment 67 Theodore Tso 2011-04-23 19:31:45 UTC Just because *I* don't like desktops that initiate I/O at random times when I don't request doesn't mean that other users shouldn't use it.
But we’re out of luck if, like most people, we’re using the default1 – with the default data=ordered, the write and pwrite syscalls can be reordered, causing the write to orig http://darrenburnhill.com/windows-10/no-bsod-just-a-crash-when-playing-prince-of-persia.html I only mentioned it because by chance I saw https://lkml.org/lkml/2011/4/3/70, which mentioned a patch to usbhid/hiddev.c at http://git.kernel.org/?p=linux/kernel/git/jikos/hid.git;a=commitdiff;h=9c9e54a8df0be48aa359744f412377cc55c3b7d2. Applications like databases expect a call to fsync() to flush pending writes to disk, and the barrier implementation doesn't always clear the drive's write cache in response to that call.

Multiuser quite important still: remote users on Windows PC:s Posted Apr 16, 2009 4:29 UTC (Thu) by eru (subscriber, #2753) [Link] Yes, but are you using EXT3 as the filesystem on External links "Linux ext3 FAQ".
