| |
Hi, We are working with a new desktop Acer Veriton Z4640G and get stumbled on failing to enter S3 suspend with kernel version 4.14 even the latest 4.15+. Here's the kernel log https://gist.github.com/mschiu77/76888f1fd4eb56aa8959d76759a912bb.
As you see, it is due to "ipmi_probe+0x430/0x430 [ipmi_si]". After the message "ipmi_si 0000:02:00.3: There appears to be no BMC at this location" shows up, then it can really go to suspend w/o problem. Although it took around 3 mins. The IPMI device is probed from PCI and here's the output of lspci https://gist.github.com/mschiu77/33f0372be41670d8a69c97e64f833087. The IPMI device is "02:00.3 IPMI SMIC interface [0c07]". We get stuck here because we don't really know why it took so long in try_get_dev_id() / ipmi_si_intf.c. Any suggestion about this to help us moving forward? Thanks
Chris
