2.5.52: PDC20268 failure

2.5.52: PDC20268 failure

[Frank van de Pol]

the 2.5 series of kernels (since early ide changes) fails on my machine when
configuring the harddisks.

machine is a dual P-II 300 MHz, Intel BX chipset
two Promise UltraTx2 boards, PDC20268, with an IBM disk connected to every channel.

kernel 2.4.18 is still running ok for me. When running a 2.5.x kernel on
this same box, the cards seem te be assigned different interrupts (weird,
since the cards remain in the same slots etc.)


2.4.18: (works fine)
ide2 at 0xa800-0xa807,0xac02 on irq 17
ide3 at 0xb000-0xb007,0xb402 on irq 17
ide4 at 0xbc00-0xbc07,0xc002 on irq 18
ide5 at 0xc400-0xc407,0xc802 on irq 18


2.5.52: (lost interrupts)
ide2 at 0xa800-0xa807,0xac02 on irq 16
ide3 at 0xb000-0xb007,0xb402 on irq 16
ide4 at 0xbc00-0xbc07,0xc002 on irq 16
ide5 at 0xc400-0xc407,0xc802 on irq 16


Regards,
Frank.

Can you tell me if 2.4.21-pre does - that has the IDE changes without
the other stuff so is a good test of which bit is involved

Also try 2.5.52 with ACPI disabled

Re: 2.5.52: PDC20268 failure - ACPI to blame !!!

Good thinking Alan! it seems ACPI is causing the trouble.

2.4.18 - OK
2.4.19 - OK
2.4.20 - OK
2.4.21-pre2 OK  (using pdc202xx_new driver)

2.5.52 with ACPI - Failure, IRQ troubles wrong IRQ assigned for promise
                   boards, lockup of box during boot
2.5.52 no ACPI   - OK !!!

What information do I need to provide to fix this problem?

Frank.
