Title:
System crashes in kswapd0 with kernel BUG at fs/inode.c:534
Status in linux-meta package in Ubuntu:
New
Bug description:
I've been getting regular systems crashes for the last few months.
Because it was being triggered in kswapd0 I recently disabled swap
completed, but the issue still continues. I also moved swap to
another disk but again the problem persists several times per week.
No other changes other than periodic ubuntu security updates.
