yes, you are right, this info is confusing.
maybe we just delete the "skipping" ?
“timer_count < 0” is caused by some firmware bug, in gtdt.c:
----
int __init acpi_gtdt_init(struct acpi_table_header *table)
{
......
if (start < (void *)table + sizeof(struct acpi_table_gtdt)) {
pr_err(FW_BUG "Failed to retrieve timer info from firmware:
invalid data.\n");
return -EINVAL;
......
}
----
But in this situation( without platform timers ), system still can work.
So I thing we just need to print a error.
