I'll add a "me too" to this list.
I don't think the problem happens in 2.0.34-UP, but I haven't tried a 2.0 kernel in a while.
Tyan Tomat III 2*P133 80meg of 70ns FP (parity with ECC enabled in the BIOS) 16meg swap located on the single (quantum lightning 730s - also happened on a 400meg seagate) scsi HD (attached to the 1522) I get lost interrupts with and without a Toshbia 4x cdrom attached I've varied between 2 IDE HD's and 1 IDE CD-ROM mixed and matched between 2 on-board IDE interfaces with the same luck.
I can't verify that the lost interrupts happen when both the scsi and ide intrefaces are busy. My test case has been compiling a kernel, but the kernel source and gcc and root are all the same partition on the scsi drive (/home is the ide).
Other things to note: My modem (biggest offender) was "com3" on irq9. irq9 doesn't have it's interrupts split among difference CPUs. Last week I bought a BT-958 and the problems completely dissappeared (the aha1522 is *still* plugged into the computer, but it is unused).
The aha1522 driver does have other problems though. I haven't had a stable SMP 2.1 kernel for a while because of scsi bus hangs when under load (make -j of the kernel). I'd get failed bus resets, corrupted command queues (the debugging dump of the pending requests I've had had 1 entry with the 'next command' pointer pointing to itself - the command list just loops forever showing the same entry). I get scsi time-outs/etc. My Quantum 730s reports a bad sector, so I know it's going to die soon. I wasn't sure for a long time that it was a scsi layer, driver or hardware problem. But I dug up another drive (the seagate 400meg) to test that theory. Getting the 958 settled the problem - it's definitely the aha152x driver.
2.1.121 is last kernel I tested. 2.1.121-UP works great (except for for the lost interrupts on the serial port). I was about to move my modem to irq 5 instead of 9 before I bought the Buslogic, but I'm not as motivated as I was then either (the 958 is a dream).
I do have written down at home the exact error messages/etc. Let me know if you want them.
