Kernel "lockup" or "busy wait" in do_get_write_access"
Last modified: 2005-10-31 17:00:50 EST
Description of problem: Kernel will enter a busy wait state will perform the file system ext3 journaling. We can recreate this bug at will. The symptoms are different depending on whether you are on a 1 or 2 cpu system and on how many processes enter the "busy wait" state. On a single cpu system you can ping or get a sysReq 't' from the console but all other access is not available. If you are on a multi-processor system and you happen to lock up only one cpu you can still gain access to system functions.. (ls, ps, console, etc.) However, you can not kill any of the "suspect" processes (even kill -9 is ignored.) as the processes seem to be in a busy loop in the kernal code. See SysReq output in Additional info field. We are seeing this very frequently because we are using named pipes (inducing file journaling) in real time mode under high performance conditions. But in searching your database this seems very similar to bugs 79257 & 79573 and the results they experience and explain are consistant with our testing. I suspect that our testing is just much more likely to expose the bug / symptom... Version-Release number of selected component (if applicable): 8.0 / 7.3 Linux How reproducible: at will / every time we run the test Steps to reproduce 1.multiple named pipes (opened under ext3 file system) 2.set processes reading / writing to these pipes to real time mode (either FIFO or Round Robin) 3.randomly read/write to the pipes under very high frequency (order of hundreds of transactions per second on each pipe) NOTE this is HW independent and we can reproduce at will in 7.3 and 8.0 Actual results: processes performing journaling enter a busy loop taking up all available CPU. Expected results: Exit busy wait state in kernel normally Additional info: Here is the sysreq 't" output. On multiple cpu systems we can observe a top running with every process below that is in the "do_get_write_access" call utilizing all of the CPU. Note that when this occurs you can still ping the system and sysReq will work even on a single CPU system...

is it possible to test the rawhide kernel with this ? It has some ext3 vs realtime fixes
Current rawhide contains a fix that addresses exactly these symptoms --- scheduling storms or realtime lockups in do_get_write_access. Please reopen if you can reproduce with a current rawhide kernel.
This is insanely disappointing!!! I find a bug we can recreated at will that hangs the kernal in 7.3 and 8.0 (both widely used) and the bug report is closed with the statement basically saying "get the next release". This is why linux will never be widely used i.e. you will never have a reliable product because bug fixes and new code are continuously put in, instead of offering fixes / patches to existing releases!
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
