Hi folks,
when booting 2.5.25 it seems that every operation to my Promise Ultra100TX2
controller attached disks ends up in having lost interrupts (lost interrupt;
pdc202xx: Primary channel reset etc. etc.). Even the partition table
detection of the disks takes forever (but it does get detected though).
I've 2 of those U100TX2 controllers in my machine. I can't tell where in the
2.5 series this problem was introduced since there was some breakage for the
MD drivers in the late 2.5 series. 2.4 kernels run fine though.
I noticed that kernel 2.5.25 binds all 4 Promise IDE controllers to IRQ 16,
while 2.4.18 uses a different IRQ for every board.
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
2.5.25: (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
Any clues?
Frank.
