Using Linus's current tree plus all the -mm gunk I get a fairly easy oops running dbench on XFS on SMP with CONFIG_DEBUG_PAGEALLOC=y: Program received signal SIGEMT, Emulation trap. 0xc0282c9d in xfs

Really? The core code (outside linux/, pagebuf/) only has a single inline. linux/ has four. pagebuf/ has three. quota/ has four. support/* some more similar to the original linux functions. That look

I just checked and the patch seems to be already in BK head. So you probably only need a bigger log if you use a recent linus- patch. Newer xfsutils will automatically create one. -Andi

hm, OK, well the code I looked at tonight had too many anyway. xfs_bawrite(), xfs_buf_undelay() and _pagebuf_iodone(). Guess I got lucky. Your patch has been merged, and is in the tree I tested.

I would still increase the on disk log size. The old defaults are showing their age. -andi

I can't hit it for some reason, but yes, I see it. As for why xfs and dbench don't mix so well - its a 2.6 thing, but having looked at what the other places which wait for I/O in the kernel do, perha

I'm also unable to hit it - do you have anything special to generate that signal to kgdb Andrew? I'm using a hacked up kdb, not kgdb, but would have expected the pagealloc debug stuff still to trip m

Nope. I can get a traditional oops by disabling kgdb in config and just running `dbench 32' on a 2-way with this .config. CONFIG_X86=y CONFIG_MMU=y CONFIG_UID16=y CONFIG_GENERIC_ISA_DMA=y CONFIG_EXPE

OK, I understand what is happening here now. Not sure why I haven't been able to trigger it, but there is clearly a bug and I have a fix which I'm testing atm. Affects both 2.4 and 2.6, but quite dif
