All,
I have an IBM 586ve SBC in an IBM Industrial PC 7587, as described here:
The machine mostly works fine, but I get these ACPI errors during boot:
[ 1.000004] mainbus0 (root)
[ 1.000004] Firmware Error (ACPI): A valid RSDP was not found (20221020/tbxf
root-275)
[ 1.000004] autoconfiguration error: acpi_probe: failed to initialize tables
[ 1.000004] ACPI Error: Could not remove SCI handler (20221020/evmisc-316)
[ 1.000004] cpu0 at mainbus0

[ 1.000004] ACPI Error: Mutex [ACPI_MTX_Tables] (0x2) is not acquired, canno
t release (20221020/utmutex-367)
Additionally, DMA is not enabled, even though it is supposed to be supported on the SIS 5597/5598 chipset:

There aren't really a lot of BIOS settings on this board, as it's an IBM SurePath BIOS system.
Has anyone else seen this issue?
Thanks!
