2. Known Issues
* Initiator mode driver shows stack trace while unloading driver. This issue
seems to be related to sysfs group not found for kobject during driver
unload.
* The hard lock up is seen when ql2xextended_error_logging and serial console is
enabled. The serial console is slow and can lead to unexpected results, if logs
are directed at higher rate. It is recommended to disable 'ql2xextended_error_logging'
while collecting logs though serial console, in case it is a must please
use "dmesg -n 1" to minimize logging.
* System crash with SCSI enclosure devices
System crashes during qla2xxx driver unload when SCSI enclosure device are being removed
by the SCSI stack.

The crash was observed with the following Kylin OS releases:
- Kylin OS 10 sp1(Kernel version: 4.19.90-23.8.v2101.ky10.aarch64)
- Kylin OS 10 sp2(Kernel version: 4.19.90-24.4.v2101.ky10.aarch64)

More details about the issue and a discussion can be found here:
https://lore.kernel.org/linux-scsi/20201128122302.9490-1-dinghui@sangfor.com.cn/
The crash is due to a bug in the SCSI Enclosure Support (ses) driver.
ses kernel module needs to be blacklisted to prevent the crash.
ses module can be blacklisted as given below:
echo "blacklist ses" >> /etc/modprobe.d/blacklist.conf
After updating the file, a reboot of the machine is needed.
