Description David Korth 2018-09-16 16:48:43 UTC

Since upgrading from 4.15.x to 4.16 (and all kernels after 4.16), connecting the UltraBase after boot (as opposed to booting with the UltraBase connected) has been unreliable with regards to the UltraBay Slim slot. Sometimes the UltraBay Slim device is recognized and shows up correctly; other times (which has been basically every time recently), the device doesn't show up, and dmesg shows an ACPI error:

[145643.405090] ACPI Error: Method parse/execution failed \_SB.PCI0.LPC.EC.IRDY, AE_AML_LOOP_TIMEOUT (20180531/psparse-516)
[145643.405103] ACPI Error: Method parse/execution failed \_SB.PCI0.LPC.EC.BEN, AE_AML_LOOP_TIMEOUT (20180531/psparse-516)
[145643.405109] ACPI Error: Method parse/execution failed \_SB.PCI0.LPC.EC.NBIN, AE_AML_LOOP_TIMEOUT (20180531/psparse-516)
[145643.405115] ACPI Error: Method parse/execution failed \_SB.PCI0.LPC.EC._Q38, AE_AML_LOOP_TIMEOUT (20180531/psparse-516)

Sometimes it also shows this message:

[175451.612897] ACPI: \_SB_.PCI0.SAT1.PRT1: docking
[175451.613125] ACPI: \_SB_.PCI0.SAT1.PRT1: Unable to dock!

Please let me know if there's any other information that would be useful for fixing this bug.

the ACPICA errors are probably related, have you checked the latest upstream kernel, say, 4.19-rc4?

please attach the acpidump output.

@erik, have you seen similar error reports and if they're fixed in upstream kernel? Let's re-evaluate the problem after the ACPICA errors are resolved first.

acpidump output (kernel 4.18.3)

Here's the acpidump output. I'll test 4.19-rc4 to see if that fixes it.

Comment 3 Erik Kaneda 2018-10-12 23:19:36 UTC

ping... Were you able to test the latest rc?

Comment 4 David Korth 2018-11-12 06:13:18 UTC

Hi,

I'm currently using 4.19.0 and it still has the same problem. Docking/undocking sometimes works after a reboot, but after some time, once the UltraBay device is removed, it can't be re-added, and it shows the same error messages.

this should be a duplicate of bug #200611.

This bug still affects me. I'm running Devuan with kernel 5.5.0-0.bpo.2-amd64 on my Lenovo X230.

This bug also affects kernels linux-image-4.19.0-8-amd64, linux-image-4.19.0-9-amd64 and linux-image-5.4.0-0.bpo.4-amd64.

Connecting the Ultrabase dock results in either the optical, hdd or ssd (whichever slim device is fitted in the dock) not being detected and the following in dmesg:

Is there a hotfix or patch I can try? Looking at bug #200611, is reverting commit 3cd091a77393 the (only) solution?
