It swaps in most of the data, but it leaves ~1700kB on the swapdevice that it doesn't manage to swap in, and apparently reads this over and over again. But it probably doesn't have anything to do with swsusp, I can reproduce it without ever having suspended, just fill up the memory so the machine swaps and then the same thing happens. Apparently kernels from -bk in late december works fine, so it's a recent introduction. Needs investigating. -- /Martin [-- Attachment #2: This is a digitally signed message part --] [-- Type: application/pgp-signature, Size: 189 bytes --] ^ permalink raw reply [flat|nested] 7+ messages in thread

Curious. I regularly check that swapoff is working (though not suspend and resume), and have not noticed this. You fill memory so the machine swaps, let the memory hog exit, then swapoff hangs indefinitely (not just taking a long time)? With no suspend+resume since booting at all? How much memory? How much swap? What .config? I'll try it tomorrow. Thanks, Hugh ^ permalink raw reply [flat|nested] 7+ messages in thread

No suspend or resume involved, just a normal boot. Steps to reproduce: 1. fill memory so it swaps 2. stop memory hog 3. swapoff -a I'm pretty sure it's an infinite loop, I left it like that while shaving. It produces the same sound over and over again as the head seeks back in order to try again and again... > How much memory? How much swap? What .config? I'll try it tomorrow. 768MB ram, 1.2GB swap, .config attached Before memory hog: # free total used free shared buffers cached Mem: 775664 110868 664796 0 4696 60420 -/+ buffers/cache: 45752 729912 Swap: 1226224 0 1226224 After memory hog: # free total used free shared buffers cached Mem: 775664 36180 739484 0 140 7224 -/+ buffers/cache: 28816 746848 Swap: 1226224 27984 1198240 After swapoff: # free total used free shared buffers cached Mem: 775664 53972 721692 0 268 11816 -/+ buffers/cache: 41888 733776 Swap: 1226224 2912 1223312 Running swapoff again produces the same behaviour and the amount of swap used does not decrease.

Looks like I'd only been testing on 3levels (HIGHMEM64G), and this only happens on 2levels. Patch below, please verify it fixes your problems. And please, could someone else check I haven't screwed up swapoff on 4levels (x86_64)? >From the likeness of the code at all levels I'd expect it to be fine, but there's nothing like a real test - thanks... The 4level mods have caused 2level swapoff to miss entries and hang. There's probably a one-line fix for that, but the error is really caused by previous awkwardness - each mask applied on two levels, an "address" that's an offset plus an "offset" that's an address. Simplify the four levels to behave in the same address/next/end way and the bug vanishes.

The patch fixes the problem completely here. swapoff after running the memory hog works as expected. and swapoff after suspend to disk and resume also works fine. Thanks for tracking this down and fixing it. -- /Martin [-- Attachment #2: This is a digitally signed message part --] [-- Type: application/pgp-signature, Size: 189 bytes --] ^ permalink raw reply [flat|nested] 7+ messages in thread
