| |
Hi,
could you please help me figure out why is that happenning:
After succesfull pivot_root & chroot from initrd, I *do* unmount /initrd, (no directories, no mapped files...), but I can *not* free the memory:
"blockdev --flushbufs /dev/rd/0" returns "BLKFLSBUF: Device or resource busy". --------------------------------------------------------------------------------------------------------------- What is keeping it busy? I got really stuck with that.
This is linux-2.4.3-pre6 SMP with devfs and blockdev from util-linux-2.11a and cramfs on initrd.
I have the following processes running at that moment: --------------------- 1 0 /bin/bash 2 1 [keventd] 3 1 [kswapd] 4 1 [kreclaimd] 5 1 [bdflush] 6 1 [kupdated] 137 1 [mdrecoveryd] 160 1 [kreiserfsd] -------------------------------------
And the following modules loaded: ------------- reiserfs raid0 md sd_mod sym53c8xx scsi_mod -----------------
I thought I've checked everything I could, but with no luck. Could that be a cramfs issue?
Thank you, Art.
