| |
Hi,
Tried latest patch with the same result - freeze...
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 <page_launder+3d/724> Trace; c0126dad <deactivate_page_nolock+13d/248> Trace; c0127e00 <page_launder+b8/724> Trace; c0128035 <page_launder+2ed/724> Trace; c0127dcc <page_launder+84/724> Trace; c0127dd0 <page_launder+88/724> Trace; c0127e00 <page_launder+b8/724> Trace; c012fd38 <try_to_free_buffers+4/138>
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.
