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.

It's a known, relatively common problem... if you're willing, ping me next
year and we can try to work through things.

PS the GOOD news is that this appears to be one of the last big bugs in
ACPI! (yay) <knock on wood>
