| |
I have an IDE lockup problem since around 2.2.8.
I compiled 2.2.12 with the ide-disk as a module. The system boots fine into single user mode. When I do "insmod ide-disk", the system hangs during the partition check.
Symtoms: . only happens with SMP . does NOT hang if boot with 'noapic' . hangs with 2.2.{8,9,10,11,12}, including 2.2.13pre14 and 2.3.18
I tried the 2.2.12-ikd patch with 2.2.12 and it detected a lockup. Copied the EIP and Call Trace down by hand and decoded from System.map manually.
FYI, I have included 2.2.8's changes to io_apic.c & irq.c below.
System info: dual PII Klamath 233MHz, CPU0:stepping 4, CPU1:stepping 3 Micronics Dual Fortress motherboard with 440FX chipset. Diamond Fireport SCSI card
Hope this IDE hang is sorted out soon...
Thanks, Delman __________________________________________________________________
