No extra patches added. running from console as root mmap002 from memtest-0.0.3 with RAMSIZE defined as 90 MB (I have 96MB) after a while with heavy disk access (thrashing?) the drive becomes silent - no more progress... [if you can not repeat this - try with less memory 32 MB...] Magic works! Magic memory Constantly LOW on inactive_clean (0 is the most common) lots of shared memory (almost equals active) [can be normal condition since mmap002 produces dirty mmaped pages] Magic process: Manual samples gave the following locations. (NOTE: not a call trace) We are trying to clean pages, but do we make any progress since disk is silent? Trace; c0127d85 Trace; c0126dad Trace; c0127e00 Trace; c0128035 Trace; c0127dcc Trace; c0127dd0 Trace; c0127e00 Trace; c012fd38 Magic Sigterm (Alt+SysRq+E) Gives you a running system again. Notes: Probably timing critical for entry into this state since adding a few printk:s makes it happen less often. I have even got complete mmap002 runs succeed - but disk is running too much and for too long time... a lot more than 10 min - normal run on previous testX did usually take less than 3 minutes. /RogerL -- Home page: http://www.norran.net/nra02596/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
