MSI-6380: APM sometimes fails to wake up

Hallo,

I have MSI-6380 (Microstar K7T 266Pro) mainboard (Athlon & KT266 based). I am using APM with lower mentioned setup.

With linux-2.4.17 it was working perfectly. Now I am using 2.4.19-pre8 with the same setup. In about 15% probablility the machine fails to be awakened from user suspend ("apm --suspend"; nor by keyboard interrupt nor case key). BIOS is set up to track keyboard IRQ.

CONFIG_PM=y
# CONFIG_ACPI is not set
CONFIG_APM=y
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
CONFIG_APM_DO_ENABLE=y
CONFIG_APM_CPU_IDLE=y
CONFIG_APM_DISPLAY_BLANK=y
CONFIG_APM_RTC_IS_GMT=y
# CONFIG_APM_ALLOW_INTS is not set
# CONFIG_APM_REAL_MODE_POWER_OFF is not set
