SubjectRe: [scsi bug] spurious build failures in aic7xxx

i should also specify the build environment:

it's a distcc setup with 5-10 hosts active at a time, so highly parallel
with large, networking related delays. It's make -j130:

nice -15 /usr/bin/time make -j130 bzImage ARCH=i386 \

the build host is a 64-bit quad CPU box, so highly parallel as well.

before this i did about a thousand x86.git builds/boots a day without
any build (or boot) failure, so i'm 100% sure that the build race was
not present before. It started triggering it a few days ago, roughly
when the commit you suspected went in.

here's all SCSI build failures logged from the past 1-2 days:

2 drivers/scsi/aic7xxx/aic79xx_reg.h
4 drivers/scsi/aic7xxx/aic7xxx.h
4 drivers/scsi/lpfc/lpfc_init.c
12 drivers/scsi/aic7xxx/aic7xxx_osm.h
108 drivers/scsi/aic7xxx/aic7xxx_inline.h
280 drivers/scsi/aic7xxx/aic7xxx_pci.c

first column is the number of error lines from logs.

When i turned off all the AICxxxx builds (all 3 drivers for good
measure), the build failures went away. [but this excludes one of my
testboxes from qa coverage - which has aic7xxx hardware - so it would be
nice to fix this.]

the host box is Fedora 8, make-3.81-10.fc8. gcc-4.2.2 crosscompiler,
built from sources. (i.e. not distro patched)
