Unfortunately I do not have your patch in this= =20 older kernel. older kernel: 2.6.28-rc5-andres-00070-g4e14e83 kernel I rean whole last week: 2.6.28-rc6-andres-00007-ged31348 There seem to have been no significant ext4 related changes to the kernel = =20 between those. for i in `seq 1 1000`;do touch tmp$i;done touch: cannot touch `tmp139': No space left on device =2E.. rm tmp*;for i in `seq 1 200`;do dd if=3D/dev/zero of=3Dtmp$i bs=3D1024k cou= nt=3D1;done dd: opening `tmp139': No space left on device 139 =2E. Various different blocksizes and filesizes all return the same result. This all hints to the patch Anesh linked. But it is included in 2.6.28-rc5.= =20 Any idea how that could happen? The kernel install is just a "make;make install; update-initramfs -c -k `ma= ke=20 kernelrelease`; update-grub" run... A short idea how I could verify on binary level what kernelrelease it reall= y=20 is? If a somehow corrupted compile (murked ccache?) is the culprit of this (in= =20 addition to my inaccuracies) I am very sorry for all your work. I let this kernel run for the next hours if you want to run some tests...
