Now I had time to test your patch on top of kernel 5.13-rc6 and 5.13.4. Can= 't test it on top of 5.14-rc2 due to bug #213803. Your patch seems to work fine and I don't get this "irq 63: nobody cared" messages and crashes any longer! However now when building stuff the G5 soo= ner or later crashes with: [...] Kernel panic - not syncing: corrupted stack end detected inside scheduler Call Trace: CPU: 1 PID: 2968 Comm: powerpc64-unkno Tainted: G W=20=20=20=20=20= =20=20=20 5.13.0-rc6-PowerMacG5+ #2 [c0000000717178c0] [c0000000005412d0] .dump_stack+0xe0/0x13c (unreliable) [c000000071717960] [c0000000000681a0] .panic+0x168/0x430 [c000000071717a10] [c000000000809ca0] .__schedule+0x80/0x840 [c000000071717af0] [c0000000000a0ea8] .do_task_dead+0x54/0x58 [c000000071717b70] [c00000000006e7b4] .do_exit+0xa14/0xa6c [c000000071717c60] [c00000000006e89c] .do_group_exit+0x50/0xb0 [c000000071717cf0] [c00000000006e910] .__wake_up_parent+0x0/0x34 [c000000071717d60] [c000000000021530] .system_call_exception+0x1b4/0x1ec [c000000071717e10] [c00000000000b9c4] system_call_common+0xe4/0x214 --- interrupt: c00 at 0x3fffa8092aa8 NIP: 00003fffa8092aa8 LR: 00003fffa7ff2d04 CTR: 0000000000000000 REGS: c000000071717e80 TRAP: 0c00 Tainted: G W=20=20=20=20=20=20= =20=20=20 (5.13.0-rc6-PowerMacG5+) MSR: 900000000200f032 CR: 22000482 XER: 00000000 IRQMASK: 0=20 GPR00: 00000000000000ea 00003fffd04ef2a0 00003fffa81b1300 0000000000000000= =20 GPR04: 0000000000000000 0000000000000000 0000000000000000 0000000000000000= =20 GPR08: 0000000000000000 0000000000000000 0000000000000000 0000000000000000= =20 GPR12: 0000000000000000 00003fffa8318c30 000000012e5ff800 00000001136b53b0= =20 GPR16: 00000001200cec38 00003fffddea1c68 00000001200ceb28 000000000000002f= =20 GPR20: 0000000000000000 00003fffa81abff8 0000000000000001 00003fffa81aaa58= =20 GPR24: 0000000000000000 0000000000000000 0000000000000003 0000000000000001= =20 GPR28: 0000000000000000 00003fffa8311c50 fffffffffffff000 0000000000000000= =20 NIP [00003fffa8092aa8] 0x3fffa8092aa8 LR [00003fffa7ff2d04] 0x3fffa7ff2d04 --- interrupt: c00 Rebooting in 120 seconds..
