Product: kernel
Component: kernel
Summary: compaq presario/evo acpi support/problem
Version: 2.4.21-0.pre4.7mdk
Platform: PC
OS/Version: All
Status: UNCONFIRMED
Severity: trivial
Priority: P2

there is a problem related to the compaq presario/evo acpi firmware related to
the HID naming. somehow compaq made the names begin with '*' character, where
normally it should not be. i have made a workaround for this on 2.5 kernels and
have been running with this patch for quite a long time without any problems
but i don't know what effect it has on other acpi machines.
in file 'drivers/acpi/namespace/nsxfname.c', function 'acpi_get_object_info()'
you can replace
259 /* Execute the _HID method and save the result */
260
261 status = acpi_ut_execute_HID (node, &hid);
262 if (ACPI_SUCCESS (status)) {
263 STRNCPY (info->hardware_id, hid.buffer, sizeof(info-
>hardware_id));
with
259 /* Execute the _HID method and save the result */
260
261 status = acpi_ut_execute_HID (node, &hid);
262 if (ACPI_SUCCESS (status)) {
263 STRNCPY (info->hardware_id, hid.buffer[0] != '*' ?
hid.buffer : hid.buffer + 1, sizeof(info->hardware_id));
there are lots of complains about it and this seems to solve the problem
although I did not try it on 2.4 kernels.
