Hi,
When try to kdump via sysrq-trigger, found kernel hung when
try to restart aacraid device, kernel print below messages:
Loading aacraid.ko
AAC0: adapter kernel faile to start, init status = 0.
Normally startup, got following message what related the devices:
Adaptec aacraid driver 1.1-5[2461]
AAC0: kernel 4.2-0[8208] Jul 6 2006
AAC0: monitor 4.2-0[8208]
AAC0: bios 4.2-0[8208]
AAC0: serial C36FA5
AAC0: Non-DASD support enabled.
Device info from lspci:

Readed driver's codes found if ignore restart device at _aac_rx_init():
Changed
if ((((status & 0x0c) != 0x0c) || aac_reset_devices || reset_devices) &&
!aac_rx_restart_adapter(dev, 0))
to
if ((aac_reset_devices || reset_devices) &&
!aac_rx_restart_adapter(dev, 0))
and get rid of reset_devices from kdump command line, kexec kernel could
bootup kernel normally, kdump would dump vmcore, looked like it caused by
aac_rx_restart_adapter() could not restart devices, it made kdump kernel
could not go on.
Any idea will appreciate~
Thanks,
Joe
