Oops in 2.1.87 shm_close with egcs... will report on gcc in a minute.

Hi, I compiled kernel 2.1.87 as UP with /proc/mtrr, and I used egcs
980122 with -)9 -mpentiumpro. This worked flawlessly in 2.1.87-pre1,
but it gave two oopses in 2.1.87 (at the bottom). Basically, I haven't
tested much (TCP seems to work... I'm sending this ;) but SB audio
doesn't work: it plays short blips of songs separated by longer
silences. So I tried quake, but it just emits a high pitches noise
after making some static at startup. However, quake (X quake) is what
got me my oops.
Hope that helps!
