Hello
When testing omap crypto driver I hit freeze/crash when modprobing tcrypt.
The result is random (crash vs freeze) but this never succeed.
I test the driver on a omap4-panda
I tested next-20200122, 5.2.21, 5.0.21 and 5.5-rc7.
On 5.0.21:

Hi,
Linux-next has huge pile of fixes in place for omap-crypto, so I would
not recommend testing any older kernels. You are saying -next crashes in
similar manner though? TI internal kernel has couple of additional fixes
against 5.4 stable, but can't see why those would help on this. If you
have spare time, you could try it out though [1].
Today's next doesn't compile for me at all for some reason (some tooling
failure) so can't really test it myself right now.
