Description David Leemans 2005-07-27 17:13:45 UTC 
Distribution: Slackware 10.1
Hardware Environment: Toshiba Satellite Pro 6000
Software Environment:
Problem Description:
/proc/acpi/toshiba entries are not created with by kernel 2.6.12.3 with
ACPI20050708. Hence it is no longer possible to get/set Toshiba specific settings. 
Plain kernel 2.6.12.2 is fine however. 


Steps to reproduce: 
boot with 2.6.12.3 patched with ACPI20050708. Notice that /proc/acpi/toshiba is
not there.

tried plain vanilla kernel 2.6.13-rc4 today, comes with ACPI20050408. Here
/proc/acpi/toshiba is missing too. 
And I do have CONFIG_TOSHIBA=y and CONFIG_ACPI_TOSHIBA=y in my .config.
When was it decided to ditch the Toshiba entries ?

Please build with CONFIG_ACPI_HOTKEY=n

Did so with plain 2.6.13-rc6, which comes with CONFIG_ACPI_HOTKEY=n by default :
still no /proc/acpi/toshiba entries.

hmmm, does it work if you boot with "acpi_specific_hotkey"?

Well yes, it does ! I will report back on trying the fix from comment #7.
Comment 12 David Leemans 2005-08-15 15:59:39 UTC 
I applied the patch to 2.6.13-rc6 and can confirm that if fixes the problem of
the missing /proc/acpi/toshiba entries. Job well done, Len !
Comment 13 Len Brown 2005-08-16 14:17:28 UTC 
linus pulled this fix in after 2.6.13-rc6 -- closing.
