Hi Himanshu， Today I reproduced the issue in my server. First, I compiled kernel 4.15-rc6 (make localmodconfig; make; make modules_install; make install), then start the kernel with parameter modprobe.blacklist=qla2xxx. Second, tail -f /var/log/syslog Third, modprobe qla2xxx ql2xextended_error_logging=0x1e400000 , the log is syslog-1e400000.txt The syslog-7fffffff is got when modprobe qla2xxx ql2xextended_error_logging=0x7fffffff BTW, I haven't load driver from 4.9.x to kernel 4.15-rc6. When I checkout kernel commit 726b85487067d7f5b23495bc33c484b8517c4074, all kernel code is 4.9.x.

Can you provide me detail steps of how you compiled 4.15-rc6. Also provide me details of how you are loading driver and also provide complete log file. I do not see how you will be able to load driver which is from 4.9.x when you compile fresh 4.15.0-rc6. Just FYI, I build test system with 8G/16G/32G adapter with 4.15.0-rc6 kernel and I am not able to see hang that you are describing. # uname -r 4.15.0-rc6+ # modprobe qla2xxx # fcc.sh FC HBAs: HBA Port Name Port ID State Device host3 21:00:00:24:ff:7e:f5:80 01:0d:00 Online QLE2742 FW:v8.05.63 DVR:v10.00.00.04-k host4 21:00:00:24:ff:7e:f5:81 01:0e:00 Online QLE2742 FW:v8.05.63 DVR:v10.00.00.04-k host5 21:00:00:0e:1e:12:e9:a0 01:06:00 Online QLE8362 FW:v8.03.06 DVR:v10.00.00.04-k host6 21:00:00:0e:1e:12:e9:a1 01:14:00 Online QLE8362 FW:v8.03.06 DVR:v10.00.00.04-k host7 21:00:00:24:ff:46:0a:5c 01:0d:00 Online QLE2562 FW:v8.03.00 DVR:v10.00.00.04-k host8 21:00:00:24:ff:46:0a:5d 01:15:00 Online QLE2562 FW:v8.03.00 DVR:v10.00.00.04-k # modinfo qla2xxx | more filename: /lib/modules/4.15.0-rc6+/kernel/drivers/scsi/qla2xxx/qla2xxx.ko firmware: ql2500_fw.bin firmware: ql2400_fw.bin firmware: ql2322_fw.bin firmware: ql2300_fw.bin firmware: ql2200_fw.bin firmware: ql2100_fw.bin version: 10.00.00.04-k license: GPL description: QLogic Fibre Channel HBA Driver author: QLogic Corporation srcversion: 6CBCF1372A7756690E83CC3 > Second, I want to find which commit introduced the issue.
