Hello,
I'm running an up-to-date Fedora 29 x86_64 (kernel 4.19.13-300.fc29.x86_64).

My ext4 file system got inconsistent twice in a week: the first time, the '/home' partition; the last time, both '/root' and '/home' partitions.
I had to use a live distro to fix it with fsck.

I ran several disk test utilities to check for HW errors, including:
* HDDScan 4.0 (http://hddscan.com/): VERIFY, READ and BUTTERFLY tests
* Diagnostics tests from Dell's BIOS
* SMART self-test
All these tests succeded: no problem detected.

If I exclude HW errors, the only other option is a SW error (in the kernel?).

Any idea?

Thank you for your help.

Marco
