Hi, I notice a regression report on Bugzilla [1]. Quoting from it: > ThinkPad L540 failed suspend deep dmesg output - Linux-6.1.27 from Debian-12 > > Since updating from Linux-4.19 to Linux-6.1.27 suspend deep is not working anymore. > (a.k.a. S3, standby or suspend to ram) > > Notebook: ThinkPad L540 20AU-S00N00 > OS: Debian-12 "Bookworm" (was Debian-10 "Buster" before) > Kernel: Linux-6.1.27 from Debian-12 (was Linux-4.19 from Debian-10 before) > > Can I provide any other helpful information? > Do you need a test with a vanilla Linux-6.1 kernel? > Should I perform any other tests or maybe try out boot parameters? > > Full dmesg output attached. > Excerpt: > rmi4_f01 rmi4-00.fn01: Failed to write sleep mode: -6. > rmi4_f01 rmi4-00.fn01: Suspend failed with code -6. > rmi4_physical rmi4-00: Failed to suspend functions: -6 > rmi4_smbus 0-002c: Failed to suspend device: -6 > rmi4_smbus 0-002c: PM: dpm_run_callback(): rmi_smb_suspend+0x0/0x40 [rmi_smbus] returns -6 > rmi4_smbus 0-002c: PM: failed to suspend async: error -6 > sd 4:0:0:0: [sda] Synchronizing SCSI cache > sd 4:0:0:0: [sda] Stopping disk > PM: Some devices failed to suspend, or early wake event detected > sd 4:0:0:0: [sda] Starting disk > OOM killer enabled. > Restarting tasks ... > rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts! > psmouse: probe of serio2 failed with error -1 > > > > Maybe related: > > 5.17-rc regression: X1 Carbon touchpad not resumed > https://lore.kernel.org/lkml/YgF%2F0QGFN4SppLKg@shikoro/T/ FYI, I guess the regression is also introduced by 172d931910e1db ("i2c: enable async suspend/resume on i2c client devices") and should have been fixed by 7b1f781f2d2460 ("Input: psmouse - set up dependency between PS/2 and SMBus companions"), but it doesn't fix the reporter's issue. Anyway, I'm adding this to regzbot: #regzbot introduced: v4.19..v6.1 https://bugzilla.kernel.org/show_bug.cgi?id=217462 #regzbot title: psmouse suspend failed on ThinkPad L540 Thanks.
