[Apologies for the resend, didn't realize I hadn't changed my GMail settings to not use HTML.] I have recently purchased a Lenovo Yoga 900 and most everything is working with a slightly modified 4.4-rc5 (https://lkml.org/lkml/2015/11/30/441 applied to enable the touchpad itself), I am seeing two issues: 1) On suspend/resume, the touchpad is non-functional. A `modprobe -r i2c-hid; modprobe i2c-hid` "fixes" it. The kernel emits: i2c_hid i2c-SYNA2B29:00: failed to reset device. dpm_run_callback(): i2c_hid_resume+0x0/0xc0 [i2c_hid] returns -61 PM: Device i2c-SYNA2B29:00 failed to resume: error -61 During the resume. So perhaps this is a timing issue (given that once resumed, the module reload does work?). 2) During boot, the following is emitted: i2c_hid i2c-ITE8396:00: error in i2c_hid_init_report size:19 / ret_size:18 I'm not sure if this indicates a hardware or driver bug? With i2c-hid.debug=1, I see: i2c_hid i2c-ITE8396:00: report (len=19): 12 00 5a ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff 06 i2c_hid i2c-ITE8396:00: error in i2c_hid_init_report size:19 / ret_size:18 Any suggestions?
