Hi! I was running xfstests #111 under the following conditions... (*) zeroed partitions, and (*) a fresh mkfs.xfs for each file system, and (1) CONFIG_XFS_DEBUG used, rtdev used, external logdev used, or (2) CONFIG_XFS_DEBUG used, external logdev used, or (3) CONFIG_XFS_DEBUG used, all internal, mkfs.xfs called with no options ...and I get a trace like the one below (from (3)). The trace is from kernel 3.9.0-rc2 on an old Pentium III, using a normal VGA console on the test PC, captured by another PC over serial cable. The trace is part of an infinite loop that becomes finite only if I rip out the console and VGA entirely. Overall, more is in play here than just XFS, but I don't know to whom I should write. [A relevant question for which I don't know the answer: Are there critical sections where you should not use assertions or call BUG() in debug code?] Something in XFS debug is fighting the console/VGA/framebuffer system, and I don't know where to go from here. You'll know you've reproduced this one because you'll need the power button to shut the PC off, so be careful. This is crash report; no fix is requested. I'm using the simple workarounds "don't run xfstests #111 with XFS debugging enabled" and "Backups! Backups! Backups!" All is well. Thanks! Michael [ 1399.347056] XFS (sda12): Corruption detected.
