aic7xxx kernel freeze...

[Ignacio Más Ivars <nacho@imit.kth.se>]

Hi all!

I have a problem that is driving me crazy. I am trying install a custom
version of the 2.4.25 kernel no matter what I do it freezes dead when
trying to load the aic7xxx driver. I have tried to compile the driver in
the kernel, as a module, both the driver and the SCSI support as a
module, I have also tried to use the old aic7xxx driver, and still the
system freezes after displaying the 'SCSI subsystem driver Revision:
1.00' message. If the aic driver is compiled in the kernel then the
system does not boot at all... and if it is a module it freezes
completely when trying to load it. Of course the first idea is that the
card is fried... but a 2.4.18-bf2.4 kernel from the installation disks
boots without a glitch and recognizes both the adaptec card and the SCSI
burner:

SCSI subsystem driver Revision: 1.00
Red Hat/Adaptec aacraid driver, Apr 14 2002
PCI: Found IRQ 11 for device 00:0a.0
spurious 8259A interrupt: IRQ7.
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.4
        <Adaptec 29160 Ultra160 SCSI adapter>
        aic7892: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs

  Vendor: PLEXTOR   Model: CD-R   PX-W1210S  Rev: 1.06
  Type:   CD-ROM                             ANSI SCSI revision: 02
(scsi0:A:4): 20.000MB/s transfers (20.000MHz, offset 16)

I have also tried to enable the firmware build option  in the kernel...
and even all kind of debug messages, which I cannot see, since the
kernel does not respond and I need to reboot each time...

Here goes my kernel config, if that helps:

#
# SCSI support
#
CONFIG_SCSI=m
CONFIG_BLK_DEV_SD=m
CONFIG_SD_EXTRA_DEVS=40
# CONFIG_CHR_DEV_ST is not set
# CONFIG_CHR_DEV_OSST is not set
CONFIG_BLK_DEV_SR=m
CONFIG_BLK_DEV_SR_VENDOR=y
CONFIG_SR_EXTRA_DEVS=2
# CONFIG_CHR_DEV_SCH is not set
CONFIG_CHR_DEV_SG=m
CONFIG_SCSI_DEBUG_QUEUES=y
# CONFIG_SCSI_MULTI_LUN is not set
CONFIG_SCSI_CONSTANTS=y
# CONFIG_SCSI_LOGGING is not set

#
# SCSI low-level drivers
#
CONFIG_SCSI_AIC7XXX=m
CONFIG_AIC7XXX_CMDS_PER_DEVICE=8
CONFIG_AIC7XXX_RESET_DELAY_MS=15000

Any hints of what can be wrong? I am running out of ideas!

Thanks in advance!
