| |
I have an SMP PenIII that had been running 2.4.1-ac18 for 65 days. Its /home partition was a newly created (first used on that kernel) ResierFS 3.6.x partition. For no obvious reason, two days ago, processes started going into uninterruptable sleeps, reportedly in "down" in the kernel.
We rebooted into 2.4.3-ac14, and suddenly we had oops and eventually panics when accessing certain parts of /home. (just an "ls" could spawn an oops, and an "ls -l" could spawn a panic). This is a production box, so unfortunately writing down the oops/panic info was the lowest priority on my list and it didn't happen.
We tried a reiserfsck with the newest reiserfsutils with both --rebuild-sb and --rebuild-tree, and neither worked.
Finally, as a last resort before returning to ext2, we tried 2.4.3 stock kernel. Magically, everything worked fine. We have yet to see any instability, and we can't make any processes stick, even under load.
This seems to be a bug somewhere in the ac patch, possibly related to SMP. If anyone could figure it out, it'd really be nice to fix this before the bug makes it way into the stock kernels.
