I did not have a chance to test a kernel until this afternoon, 7-28-97.
Hardware: Tyan Tomcat II, 2 120s overclocked to 133, EIDE disks, 64M RAM.
With PEND_INTS uncommented, things work fine. Boots, runs fine. Only
problem is my kernel compile times went up again! Here is a table of my
kernel compiles over the last week or so:
MP Kernel from 7-23-97 with -j 8:
313.71 real 425.41 user 104.29 sys
MP Kernel from 7-19-97 with -j 8:
310.99 real 414.62 user 103.70 sys
UP Kernel from 7-19-97 with -j 8:
394.42 real 345.08 user 30.46 sys
UP Kernel from 7-19-97 with no -j:
448.67 real 340.57 user 23.72 sys
MP Kernel from 7-28-97 with -j 8:
330.72 real 442.82 user 114.30 sys
Is this mostly due to the EIDE disks? All of these compiles are from a
fresh reboot in multi-user mode with one user, no X, nothing else running.
