--- Comment #52 from Matthew Stapleton (matthew4196@gmail.com) ---
I'm a bit late to reporting this, but it might be related to this bug report.
Since noticing this 100% cpu flush problem on my computer with a non-raid
Samsung SSD 990 PRO NMVe and kernel 6.6.3 (and now 6.6.8) I decided to do a git
bisect and seemed to track down the problem to commit:
7e170922f06bf46effa7c57f6035fc463d6edc7e if that helps, although I haven't
tested if disabling CR1_5 also resolves the problem. Running "tar xf
linux-6.6.8.tar.xz" is enough to trigger 100% cpu for a few seconds after tar
is finished on my system, although it doesn't noticeably trigger the problem on
my server with raid 6 and hard drives. It also looks like my ext4 filesystem
is mounting with stripe=32733 according to /proc/mounts, although dumpe2fs -h
doesn't show any stripe settings on the filesystem.
I'll try the patch and see if it fixes the problem.
