Dear SeaBIOS folks,
coreboots board status repository has some SeaBIOS warnings, and I believe the keyboard doesn’t work in that case.
``` $ git grep 'Timeout at i8042_flush' origin/master -- origin/master:amd/lamar/4.0-9540-gae5ab60/2015-04-30T02:12:19Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:amd/olivehill/4.0-7005-gb9a0809/2014-10-08T13:44:17Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:amd/olivehillplus/4.0-6942-g4177db5/2014-09-19T19:38:48Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:amd/thatcher/4.3-102-g380e167/2016-02-04T18_30_40Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:aopen/dxplplusu/4.5-485-g52896c6/2016-12-04T02_03_58Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:gizmosphere/gizmo/4.0-9564-g58649b0/2015-05-03T07:14:33Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:google/panther/4.0-9491-g64c7791/2015-04-23T21:31:14Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:google/panther/4.1-340-gb38b0f2/2015-08-25T18:38:10Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:google/panther/4.3-777-g4774bb9/2016-04-18T13_11_58Z/coreboot_console.txt:|7f6bc000| WARNING - Timeout at i8042_flush:71! origin/master:hp/2760p/4.5-906-g3fb6e6e-dirty/2017-01-27T03_04_14Z/coreboot_console.txt:|7feca000| WARNING - Timeout at i8042_flush:71! origin/master:hp/2760p/4.5-911-g9510156/2017-01-28T14_47_33Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:hp/2760p/4.5-913-g0f70fbd/2017-01-29T02_16_08Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:intel/bayleybay_fsp/4.0-6293-g0b4b230/2014-06-25T23:32:28Z/coreboot_console.txt:|7ba9a000| WARNING - Timeout at i8042_flush:71! origin/master:intel/minnowmax/4.2-429-g4013469/2015-11-30T20_21_41Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:intel/minnowmax/4.2-429-g4013469/2015-11-30T20_21_41Z/tests/cbmem-console.log:WARNING - Timeout at i8042_flush:71! origin/master:intel/minnowmax/4.5-306-g00ad7ff/2016-11-17T17_00_43Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:intel/minnowmax/4.5-306-g00ad7ff/2016-11-17T17_00_43Z/tests/cbmem-console.log:WARNING - Timeout at i8042_flush:71! origin/master:pcengines/alix2d/4.0-6723-ga0a3727-dirty/2014-08-15T23:01:34Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:pcengines/alix2d/4.0-6723-ga0a3727/2014-08-15T01:44:46Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:pcengines/apu1/4.4-422-g9aba60e/2016-06-05T08_06_37Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:pcengines/apu2/4.5-801-gfeb4ef6/2017-01-11T16_15_42Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! origin/master:siemens/mc_tcu3/4.4-108-g0d4e124/2016-05-09T06_14_45Z/coreboot_console.txt:WARNING - Timeout at i8042_flush:71! ```
I also experience this sometimes on a Lenovo X60, when I load the SeaBIOS ELF file from GRUB with the commands below.
```
chainloader (cbfsdisk)/img/seabios boot
```
Every time, the keyboard doesn’t work – on the Lenovo X60 it’s connected over the PS/2 port – the error message `Timeout at i8042_flush:71!` can be seen.
Note, that it’s unlikely to be a timing issue, as the keyboard works in the GRUB payload *before*.
Any idea, what causes the problem, and is there a way to fix it?
Thanks,
Paul
