Fedora Core 1 reboots after loading initrd on HP Compaq Presario S7299I
Last modified: 2007-11-30 17:10:46 EST
Description of problem: Kernel 2.4.22 included in Fedora Core 1 can't boot on my HP Compaq Presario S7299I PC, since it reboots just after starting loading initrd. Older kernels until 2.4.21 (from RH 9) run ok. I investigated doing some hacking inside kernel code and I found what follows: the function acpi_find_rsdp, called inside acpi_table_init (see file tables.c under the drivers/acpi folder) during the kernel initialization phase finds a corrupted acpi_table_rsdp structure. The revision field of the returned acpi_table_rsdp structure seems to be >= 2, so the next call to acpi_table_compute_checksum passes the value of "((struct acpi20_table_rsdp *)rsdp)->length" as length parameter. This value is probably not correct and this causes a memory access violation during memory scanning inside the acpi_table_compute_checksum function and subsequently the machine reboots. My impression is that my machine BIOS (Phoenix Technologies, LTD, Version: 3.09, Release Date: 03/25/2004) does not follow correctly ACPI standard. Everything goes fine simply passing from GRUB to kernel the acpi=off initialization option. This is the output of the first three entries given by dmidecode: # dmidecode 2.2 SMBIOS 2.3 present. 40 structures occupying 1184 bytes. Table at 0x000F0000. Handle 0x0000 DMI type 0, 20 bytes.
