I am using the Product: Dell Wireless 1450 Dual-band (802.11a/b/g) USB 2.0 Adapter
This relies on the p54usb driver. It works great on kernel 4.18. I upgraded to 5.0.0-3 and the device fails to start.
On the older kernel, things seem good:

Description: Ubuntu 18.04.3 LTS
Release: 18.04 |
== SRU Justification ==
User report that the p54usb driver will crash when trying to load it on 5.0 kernel for a Dell Wireless 1450 Dual-band (802.11a/b/g) USB 2.0 adapter. This was caused by commit e3554197 (p54: Use skb_peek_tail() instead of direct head pointer accesses.)
== Fix ==
* 1645ab93 (p54: fix crash during initialization)
This patch added a check for target_skb to determine where to queue the buffer. It can be cherry-picked into Disco.
Eoan got this patch from v5.2.1 upstream stable release update.
== Test ==
Test kernel could be found here:
https://people.canonical.com/~phlin/kernel/lp-1839693-p54usb/
This issue was reported against Bionic HWE 5.0 kernel, user confirmed that the patched B-hwe kernel works as expected.
== Regression Potential ==
Low, change limited to p54usb driver, patch tested with positive test result.
== Original Bug Report ==
